Iwill like to know how to solve this

x = 2

Collect terms in x to one side of the equation and numeric values on the other side.

1 + 4x = - 5 + 7x ( subtract 7x from both sides )

1 + 4x - 7x = - 5

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 6 ( divide both sides by - 3 )

x = = 2

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
