David is right times older than Nicole. If David is 32 years old , how old is Nicole? Write an equation to solve Nicole's age. Let a be the age of Nicole. An equation that can be solved for Nicole's age is .​

8a=32

Step by Step

Since David is 8x older than Nicole you could write Nicole as the age of a, so then David would be 8a. You are given David is 32 years old so you set 8a equal to 32.

Answer is 4

Nicole is 4 years old

8a=32

divide both sides by 8

Answer is 4

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
