-2/3x+y=8 solve for y

Answer:8 Yards

Step-by-step explanation:

168/12=14 yards long.

14-6=8

The unpainted strip is 8 yards long.

Answer:

The unpainted strip in each part of the​ field is 8-yards-long

Step-by-step explanation:

168 divided into 12 equal parts would be: 168/12=14

and a 6-yard-long strip in each of those 14 parts would leave 8 yards unpainted in each of the 14 strips: 14-6=8

Answer:

D

Step-by-step explanation:

A is incorrect because 5 cubed is not -125. it is positive 125.

B is incorrect because -3 cubes is not 27, it is negative 27.

C is incorrect because -10 squared is also 100, not only 10 squared.

D is correct because both -12 squared and 12 squared equal 144.

Answer:

D

Step-by-step explanation:

Answer:

7\(\pi\) cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = \(\pi\)r²

A = \(\pi\)(3)²

A = 9\(\pi\)

Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)

A = \(\pi\)r²

A = \(\pi\)(1)²

A = \(\pi\)

Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:

9\(\pi\) - \(\pi\) - \(\pi\) = 7\(\pi\)

So, the area of the shaded region is 7\(\pi\) cm²

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

How to calculate the circumference of a circle?

To calculate the circumference of a circle we must apply the following formula:

2R

R = Radius of the circle.

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

21 = 6.28

22 = 12.59

So, to find the difference between the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

12.59 - 6.28 = 6.31

According to the above, the difference in the circumferences would be 6.31 cm.

Answer:

The X is equal to 1.75

Step-by-step explanation:

3.5X2.25=7.875

14/7.875=1.75

Answer: x=1.75

Step-by-step explanation:

rearrange the term: 3.5 (2.25 + x) = 14

the new term: 3.5 (x + 2.25) = 14

Combine multiplied terms into a single fraction, then distribute.  

x = 1.75

Answer:

1.) Let x be the number. The inequality can be written as:

x + 7 < 18

Subtracting 7 from both sides, we get:

x < 11

Therefore, the number is less than 11.

2.) Let x be the number. The inequality can be written as:

x + 5 > 26

Subtracting 5 from both sides, we get:

x > 21

Therefore, the number is greater than 21.

3.) Let x be the first integer. The second integer is x+1. The inequality can be written as:

x + (x+1) < 55

Simplifying, we get:

2x + 1 < 55

Subtracting 1 from both sides, we get:

2x < 54

Dividing both sides by 2, we get:

x < 27

Therefore, the largest possible first integer is 26, and the second integer is 27. Their sum is 53.

4.) Let w be the width of the rectangle. The length is 4cm longer than the width, so the length is w + 4. The perimeter is given by:

2(length + width) ≤ 28

Substituting the expressions for length and width, we get:

2(w + 4 + w) ≤ 28

Simplifying, we get:

4w + 8 ≤ 28

Subtracting 8 from both sides, we get:

4w ≤ 20

Dividing both sides by 4, we get:

w ≤ 5

Therefore, the maximum possible width is 5cm, and the maximum possible length is 9cm.

5.) Let x be the first odd integer. The second and third odd integers are x+2 and x+4, respectively. The inequality can be written as:

x + (x+2) + (x+4) ≥ 51

Simplifying, we get:

3x + 6 ≥ 51

Subtracting 6 from both sides, we get:

3x ≥ 45

Dividing both sides by 3, we get:

x ≥ 15

Therefore, the smallest possible first odd integer is 15, and the second and third odd integers are 17 and 19, respectively. The middle integer is 17.

Answer:

A

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

Answer:

C

Step-by-step explanation:

I would first try to get that fraction into x/100 because 100 is the easiest to work with.

In order to get from 40 to 100, you multiply by 2.5

So we should multiply 29 by 2.5 also to make it evened out.

29 x 2.5 = 72.5

72.5/100

Now we will move the decimal two places to the left on both sides because 100. is the same as 100

72.5/100. turns into .725/1

The closest thing to .725 is .7

Answer: Remove, Multiply, Add (RMA)

Step-by-step explanation:

I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Answer: what they

Step-by-step explanation:

Answer: A

Step-by-step explanation:

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
