Four times a number minus 5 is the
same as twice the number plus 3.

The number is 4

Step-by-step explanation:

Lets say the number is x:

4x-5=2x+3     subtract 3

4x-8=2x       divide by 2

2x-4=x

x+4=2x

x=4

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
