Answer 7

To solve for x, we first need to isolate the variable.

Adding 12 to both sides of the equation, we get:

ax = 9 + 12
ax = 21

Now, to solve for x, we divide both sides of the equation by a:

x = 21/a

So, x equals 21/a.

Answer 8

The area of a rectangle is calculated with the formula A=lw. If the area of a rectangle is 52.5 m2 and the width is 5 m, what is the length? Explain the solution to the real-world problem.(1 point)
Responses

l=10.5
l equals 10.5

The length is 262.5 m.
The length is 262.5 m.

The length is 262.5 m2.
The length is 262.5 m squared .

The length is 10.5 m.

Answer 9

To find the length of the rectangle, we can rearrange the formula for the area of a rectangle:

A = lw

Given that the area is 52.5 m2 and the width is 5 m, we can substitute these values into the formula:

52.5 = 5 * l

To solve for l, we divide both sides of the equation by 5:

l = 52.5 / 5

l = 10.5

Therefore, the length of the rectangle is 10.5 meters.
