Answer: Option B) The football team gained 3 yards in one play. The football team lost 7 yards in the next play
Step-by-step explanation:
The expression 3 + (-7) represent initial gain of 3 yards followed by a loss of 7 yards.
- The gain of 3 yards is 3 (i.e forward movement by 3 yards)
- The loss of 7 yards is -7 (i.e backward movement by 7 yards)
So, 3 + (-7)
= 3 - 7
= -4 (i.e the football team lost more yards of 4 than gained)
