7B + 4 = 7B - 3
We need to solve for B
Let's add 3 in both sides:

7B + 4 = 7B - 3
7B + 4 + 3 = 7B - 3 + 3
7B + 7 = 7B

Let's subtract 7B from both sides:
7B + 7 = 7B
7B - 7B + 7 = 7B - 7B
7 = 0

7 = 0, which is impossible. 7 can never be 0, and 0 can never be 7.
So the equation have no solution.

The red strip will be cut into <br>pieces that are 1/2 foot long. How many pieces will there be?
SashulF [63]

15 pieces will there be.

<h3> How many pieces will there be?</h3>

 .5 is the same as  1/2, while 7.5 is the same as 7 1/2. To determine how many strips may be cut, use the following expression:

.5x = 7.5

This is due to the fact that the ribbon length that has to be cut is .5 feet, and we are attempting to determine how many pieces of that length might be cut from a roll of ribbon that is 7.5 feet long.

Divide both sides by 2.5 to separate the variable, and that's all there is to it.

7.5/.5 is 15.

x = 15.

Eli is able to slice a ribbon into three pieces that are each .5 feet long.

The complete question is: The red strips that are  1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression could be one of the steps in determining how many strips can be cut?
