Answer 1

Using proportions, it is found that the signed number -15 represents the team's total loss of yards on the 3 plays.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, in one play, the team lost 5 years, that is, the amount is -5. What is the amount on three plays? The rule of three is given by:

1 play - -5 yards

3 plays - n yards

Applying cross multiplication:

n = 3 x (-5) = -15.

The signed number -15 represents the team's total loss of yards on the 3 plays.
