A football team has a net yardage of -34 1/3 yards on a series of plays. The team needs a net yardage of 20 yards to get a first down. How many yards do they have to get on their next play to get first down?

54 1/3 yards

Step-by-step explanation:

Yards needed = Required net yards - Yards already ran

We know that Required net yards = 20

We can set yards already ran to -34 1/3

Yards needed = (20) - (-34 1/3)

= 20 + 34 1/3                   Subtracting a negative makes it a +

= 54 1/3

They have to get 54 1/3 yards on their next play to get a first down
