The sum of 7 times a number and 3 is 5 please write as an equation (use y for unknown number)

y = 2/7

Step-by-step explanation:

7y+3 = 5

Subtract 3 on both sides getting 7y = 2

Then divide everything by 7 to isolate the variable y which gets y = 2/7

Therefore the number that multiplies times 7 and adds 3 to get 5 is 2/7.

Hope this helps

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
