If A = -3n + 2, and B = 5n - 7, what is the value of A + B, in simplest form?

2 n - 5
-8 n - 5
-3 n
2 n + 9

Answers

Answer:

2n - 5

Step-by-step explanation:

Pre-Solving

We are given that A is -3n + 2 and B is 5n - 7.

We want to find the value of A + B in its simplest form

Finding it in its simplest form means we combine all of the like terms together.

Solving

We can replace A with -3n + 2 and B with 5n -7

A + B => -3n + 2 + 5n - 7

Combine the terms with n together.

-3n + 5n = 2n

Combine the numbers together.

2 - 7 = -5

Now, add 2n and -5 together.

2n + -5

This can be simplified to be:

2n - 5

This expression can't be simplified anymore, so this means that 2n - 5 is its simplest form.

Answer:

2n-5

Step-by-step explanation:

to solve this problem, you would have to add (-3n+2)+(5n-7). -3n+5n=2n and 2+(-7)=-5. Therefore, A+B=2n-5.

Answer:

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer: A

Step-by-step explanation:

$\frac{J}{H} = G + \frac{I}{H}$ >Since you are solving for H bring I/H to the other side

by subtracting I/H from both sides

$\frac{J}{H}- \frac{I}{H} = G$ >There is a common denominator so you can

combine the fractions

$\frac{J-I}{H} = G$ >Multiply both sides by H or cross multiply whichever

way your mind things about how to get H on top

$J-I = G(H)$ >Divide both sides by G

$\frac{J-I}{G} = H$ >Answer is A

a. 4 1/4 feet
b. 4 1/2 feet
c. 12 3/4 feet
d. 13 1/4 feet

Answers

13 1/4

4.5 into a fraction is 4 1/2. 4 1/2 + 8 3/4 is 13 1/4 feet.

Answer:

The answer is d. 13 1/4 feet PLEASE MARK BRAINLIEST

Step-by-step explanation:

the 8 feet plus the 4 feet from the 4.5 feet makes 12 feet plus the fractions so 8 inches is 1/4 feet and 8 inches plus 5 inches on the 4.5 feet makes 13 inches which is 13 1/4 feet so 8 3/4 feet + 4.5 feet = 13 1/4 feet

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Answer:

The solution is ([4], [19]).

Step-by-step explanation:

To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:

y = 4x + 3 (Equation 1)

y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:

y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)

4x - 3x = 7 - 3

x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

y = 4(4) + 3 (Substituting x = 4)

y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

A line segment goes from one point to another point on the circle and goes through point G. It has a length of 10. Circle H is shown. A line segment goes from one point to another point on the circle and has a length of 20.

Answers

Answer:

Circle with 20 unit Diameter

Step-by-step explanation:

There's no picture attached, so I can't tell you which circle that is, but remember that the radius is equal to half of the diameter. The diameter is a segment on the interior of a circle that passes through the center. You could also find a ten-unit-long line with a segment from the center of the circle to any point on the circle, because that is the radius. If it doesn't pass through the center, it's a chord, not a diameter, so it doesn't count!

The circle with a radius of 10 is (d) A line segment goes from one point to another point on the circle and has a length of 20.

What is radius?

The radius of a circle is a line drawn from the center to the circumference of the circle

For a circle to have a diameter of 20, the radius of the circle must be 10

The circle with a radius of 10 is (d) A line segment goes from one point to another point on the circle and has a length of 20.

Answers

Answer:

Step-by-step explanation:

total surface area-(lh+wh+lw)

don't forget to put it in square units!

HOPE THIS HELPS!

The surface area of the rectangular prism would be four times greater. Let’s say you had a rectangular prism with a length of 2, width of 3, and a height of 4. You would do 2( W•L + H•L + H•W) which in this case is 2(3•2 + 4•2 + 4•3) which would get you a surface area of 52.

Now if you were to double the dimensions, the new length would be 4, width would be 6, and the height would be 8. You would also do 2( W•L + H•L + H•W) which in this case is 2( 6•4 + 8•4 + 8•6) which is 208. Therefore, the surface area is 4 times greater.

Answer:

Step-by-step explanation:

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Step-by-step explanation:

Let's call the number of rotten peppers "r".

We know that Mr. Henry paid $325.00 for the bag of peppers, and there were 400 peppers in the bag. So, the cost per pepper is:

325/400 = $0.8125

Now, let's look at the selling price. Mr. Henry sold the good peppers in heaps of 5 for $10.00 per heap, which means he sold each pepper for $2.00.

Let's call the number of good peppers "g".

The total revenue from selling the good peppers is:

5*(g/5)*$10.00 = $10g

We know that Mr. Henry made a profit of $375.00, so:

$10g - $325.00 = $375.00

$10g = $700.00

g = 70

So, Mr. Henry had 70 good peppers.

We can use this information to find the number of rotten peppers:

r + g = 400

r + 70 = 400

r = 330

Therefore, Mr. Henry bought 330 rotten peppers.

Brainlist for positive attitude and correct answer :D

Answers

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
