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?
Answer:
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
When the length of the blue ribbon is 10 inches then the length of the red ribbon is 3 inches, when the length of the blue ribbon is 27 inches then the length of the red ribbon is 20 inches, and when the length of the blue ribbon is 'x' inches then the length of red ribbon is (x - 7) inches.
Given :
Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches than the length of a piece of blue ribbon.
a) The length of the blue ribbon is 10 inches.
Red ribbon length = 10 - 7 = 3 inches
b) The length of the blue ribbon is 27 inches.
Red ribbon length = 27 - 7 = 20 inches
c) The length of the blue ribbon is x inches.
Red ribbon length = (x - 7) inches
