5(3x+2)=8(2x-4) solve for x

x = 42   i hope this helps!   :)

Step-by-step explanation:

given   5(3x + 2) = 8(2x - 4)

distribute the 5 to both the 3x and the 2   15x + 10 = 8(2x - 4)

now distribute the 8 to both the 2x and the -4   15x + 10= 16x - 32

subtract 15x from both sides   10 = x - 32

add 32 to both sides   42 = x

flip the equation around so the x is first   x = 42

answer   x = 42

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
