x = 2/3

y = 4/3

Step-by-step explanation:

y = 2x    ----------------(I)

x = -y + 2      -----------------(II)

substitute y =2x in equation (II)

x = -2x + 2

x +  2x = 2

     3x = 2

      x = 2/3

Plugin x = 2/3 in equation (I)

y = 2 *

y = 4/3

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
