What is 2x – 45 = 7x – 9x –x

Hi,

2x - 45 = - 3x

2x + 3x = 45

x = 45/5 = 9.

x=9

Step-by-step explanation:

2x-45=7x-9x-x

2x-45= -3x

5x=45

x=9

i believe the answer is 68cm

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
