9 was subtracted from a certain number and the result was divided by 4. If the final answer is 5, what was the original number?

let the number be X

Step-by-step explanation:

(x - 9)/4 = 5

or. x - 9 = 5 × 4

or. x = 20 + 9

x = 29

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
