Is it possible to solve 5(b-2)=20 by first dividing each side by 5? explain

Yes

5(b-2) = 20

b-2 = 4

b = 6

Yes

Step-by-step explanation:

It is indeed. This simplifies the equation. What you have to remember about solving equations is whatever you do to one side you have to do the same to the other side. This maintains the 'balance'.

Dividing by 5 gives b - 2 = 4

so b =6.

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

i think the answer is b.

step-by-step explanation:

not 100% sure though.
