Solve the equation. Then check your solution. -2/5 + a = 1/5

a. 3/5
b. - 1/5
c. 3/10
d. - 3/5

A: 3/5

Step-by-step explanation:

-2/5 + a = 1/5

add -2/5 on both sides

a = 1/5 + 2/5

a = 3/5

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

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
