Which of the following equations has a solution of x = -5?
a. Equation A
b. Equation B
c. Both A and B
d. Neither A nor B
Answer:
C. Both A & B
Step-by-step explanation:
Solve the equations given:
Equation A:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 11x and add 7 to both sides:
16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)
16x - 11x = -32 + 7
Simplify. Combine like terms:
16x - 11x = -32 + 7
5x = -25
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (-25)/5
x = -25/5
x = -5
Equation A is an answer choice.
Equation B:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 & subtract 2x from both sides:
-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)
-4x - 2x = 20 + 10
Simplify. Combine like terms:
-4x - 2x = 20 + 10
-6x = 30
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (30)/-6
x = 30/-6
x = -5
Equation B is also an answer choice.
C. Both A & B is your answer.

Norma bought a plastic bag that contains 100 balloons. The label on the bag says that there are 20 each of blue, yellow, red, green, and orange balloons. Norma will take one balloon from the bag at random. What is the probability that the balloon will be either red or blue?
A)3/2
B)2/3
C)3/5
D)2/5
Answer:
d
Step-by-step explanation:
ur welcome plz mark brainliest
2/5 t is the probability that the balloon will be either red or blue.
Thus option A is correct.
What is probability?The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.
The probability of the event will be taken as
The fact that the data of red and blue will have a chance of occurring in the event
The first draw chance would be 20/100 = 1/5
The second draw would be 20/100 = 1/5
P = 20 / 100 + 20 / 100
P = 1/5 + 1/5
P = 2/5
Therefore, option D is the correct option.

The table shows the price of bagels at two different stores:
Store Price Bagels
Bagel Stop $6.00 15 bagels
Yummy Bagels $14.00 35 bagels
Yummy Bagels sells bagels at a lower unit price than Bagel Stop. (3 points)
Select one:
True
False
Answer:
false
Step-by-step explanation:
the unit price for both is $0.4
Answer:
False
Step-by-step explanation:
Bagel stop sells 15 bagels for 6 dollars, dividing 15/6, you get that you get 2.5 bagels per dollar. Whilst Yummy bagels sells 35 bagels for 14 dollars. Diving 35/14 you get 2.5 as well. Therefore this is false.
Find the solution set of the inequality.
10c + 5 ≤ 45
The cost of a car rental is $30 per day plus 20 cents per mile. You are on a daily budget of $94. Write and solve an inequality to find the greatest distance you can drive each day while staying within your budget. Find 2 other two-step inequalities with the same solutions.
STEP 1
determine inequality
Car rental= $30 per day
Mileage= $0.20 per mile
m= number miles driven
Add daily rental charge to the quantity of (number of miles driven multiplied by the per mile charge). This has to be less than or equal to the budget of $94 a day.
$30+ ($0.20 * m) ≤ $94
$30 + $0.20m ≤ $94
STEP 2
solve
$30 + $0.20m ≤ $94
subtract 30 from both sides
0.20m ≤ 64
divide both sides by 0.20
m ≤ 320 mile limit
ANSWER:
Inequality: $30 + $0.20m ≤ $94
320 miles is the daily mileage limit and can be driven daily to stay under (or equal to) the $94 daily budget.

Jillian and Dawn are playing a game of miniature golf. In this game, the score on a hole is the number of putts it takes to get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian’s mean is 2.4 and Dawn’s mean is 3.3. Which explains who won the game?
Jillian won the game because her score varied less than Dawn’s score.
Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
Dawn won the game because the person with the greater mean played better.
Dawn won the game because her mean absolute deviation was less than Jillian’s.

Answer: y = -1/4x - 6
Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.
Answer:
-1/4x + -6
Step-by-step explanation:
The slope is -1/4 because slope = \(\frac{rise}{run}\),
So:
-\(\frac{1}{4}\) is the slope, also is negative.
The y intercept is -6 because it passes through -6 at the y axis.

Answer: To find the mean of a data set, add all the numbers together, then divide the answer by how many numbers there were
Step-by-step explanation:
Example: 1,5,2,6,9,4
First add them all so 1 + 5 + 2 + 6 + 9 + 4 = 27
Then divide by how many numbers there were so 27/6=4.5
4.5 is the mean of the data set
Which of the following formulas would find the surface area of a right cylinder
where h is the height, ris the radius, and BA is the base area?
Check all that apply.
A. 2pi^2 + 2pi rh
B. BA + 2 pi rh
C. BA + pi r^2
D. Pi r^2 + pi rh
E. 2 pi r^2
Answer: a and b
Step-by-step explanation:
The formulas which can be use to find the surface area of a right cylinder is 2πr² + 2 πrh and BA+2πrh.
What is surface area of cylinder?Surface area of cylinder is the area of each faces by which it is enclosed.
The surface area of cylinder can be calculated with the following formula;
A = 2πr²+2πrh
Here, (h) is the height of the cylinder and (r) is the radius.
here, we have,
we know that,
A = 2πr²+2πrh
This formula is similar to the option A. Thus, the option A is correct. The base of the cylinder is circular and there are two circle at the base of a cylinder.
The base area of the cylinder is,
BA =2πr²
Put this value in the surface area formula of cylinder as,
A = BA+2πrh
Thus, the option B is also correct.
Hence, the formulas which can be use to find the surface area of a right cylinder is 2πr² + 2 πrh and BA+2πrh.
