Write a subtraction equation to represent the two consecutive plays and the net yardage. Explain your answer.


A) 4 yards
B) -7 yards
C) -3 yards
D) 7 yards

Answer 1

The subtraction equation to represent the football quarterback's net yardage after two plays is 4 yards - 7 yards, resulting in a net loss of 3 yards.

Step-by-step explanation:

The student is asking to write a subtraction equation to represent the net yardage gained or lost by the quarterback in two consecutive plays. To find the net yardage, we subtract the yards lost from the yards gained. On the first play, the quarterback gained 4 yards, and on the next play, he lost 7 yards. Therefore, the subtraction equation would be:

Net yardage = 4 yards - 7 yards = -3 yards.

This means the quarterback has a net loss of 3 yards over the two plays. In this equation, the sign change in subtraction indicates that the quarterback has lost yardage.
