Question:

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.

How long is the red ribbon if the length of the blue ribbon is:

10 inches?

27 inches?

x inches?

a) Length of red ribbon is 3 inches

b) Length of red ribbon is 20 inches

c) Length of red ribbon is (x - 7) inches

Solution:

Given that,

The length of a piece of red ribbon should be 7 inches than the length of a piece of blue ribbon

Therefore,

Length of red ribbon = length of blue ribbon - 7 eqn 1

We have to find the length of red ribbon if the length of the blue ribbon is:

a) length of blue ribbon = 10 inches

Therefore, from eqn 1,

Length of red ribbon = 10 - 7

Length of red ribbon = 3

Thus length of red ribbon is 3 inches

b)  length of blue ribbon = 27 inches

Therefore, from eqn 1,

Length of red ribbon = 27 - 7

Length of red ribbon = 20 inches

c) length of blue ribbon = x inches

Therefore, from eqn 1,

Length of red ribbon = x - 7

Thus length of red ribbon is (x - 7) inches
