Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon. a. How long is the red ribbon if the blue ribbon is:
10 inches?
27 inches?
X inches?

If blue ribbon is 10 inches, red ribbon is 3 inches

If blue ribbon is 27 inches, red ribbon is 20 inches

If blue ribbon is x inches, red ribbon is x - 7 inches

Step-by-step explanation:

Given that,

Need to find,

How long is the red ribbon if the blue ribbon is 10 inches?

We know that the formula for find the length of the red ribbon is:

length of blue ribbon - 7 inches = length of red ribbon

Since we know the length of the blue ribbon (10 inches), we can apply that to the formula:

10 inches - 7 inches = length of red ribbon

So, what is 10 - 7? That gives us 3. So, the length of the red ribbon is 3 inches if the length of the blue ribbon is 10.

How long is the red ribbon if the blue ribbon is 27 inches?

We do the same as we did above to get 20 inches as the final answer because 27 inches - 7 inches gives us 20 inches as a difference.

How long is the red ribbon if the blue ribbon is x inches?

Since we do not know the value of x, we keep the length of the red ribbon to x - 7.

If blue ribbon is 10 inches, red ribbon is 3 inches

If blue ribbon is 27 inches, red ribbon is 20 inches

If blue ribbon is x inches, red ribbon is x - 7 inches
