I've got x/7 = -9 for the first step but I don't know how to get rid of the 7, is it × or ÷?

7 - x/7 = -2

Subtract 7 from both sides:

x/7 = -9

Multiply both sides by 7:

x = -63

Step-by-step explanation:

To seperate the variable from the number we should subtract both sides from 7

7-x/7 ( -7 ) = -2 -7

= x/7 = -9

Now to seperate the variable from 7 in L.H.S we need to multiply both the sides with 7

x/7 (7) = -9(7)

= x = -63

So the answer will be -63

Hope it helps you!!

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
