Sherry uses the steps below to solve the equation x+ (-8) = 3x+6

step 1

step 2

step 3

step 4

add 1 negative x-tile to both sides and create zero pairs

add 8 positive unit tiles to both sides and create zero pairs.

divide the 14 unit tiles evenly among the 2 x-tiles

the solution is x= 7

what is sherry's error?

See explanation

Step-by-step explanation:

Sherry has the equation

1 step: Add 1 negative x-tile to both sides and create zero pairs:

2 step: Add 8 positive unit tiles to both sides and create zero pairs:

3 step: Add 14 negative unit tiles to both sides and create zero pairs:

4 step: Divide the 14 negatuve unit tiles evenly among the 2 x-tiles:

5 step: The solution is

Or Sherry can combine step 2 and 3 and having the equation add 6 negative unit tiles to both sides and create zero products:

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
