Final answer:
After starting on the 20-yard line and going through a series of plays with gains and losses, the football team will start their next play on the 25-yard line.
Step-by-step explanation:
The student has provided information about the gains and losses of yards on a series of plays by a football team. Starting from the 20-yard line, we need to calculate the total yardage gained or lost over the course of four plays. We can represent this with an equation:
Starting yard line + Gain/Loss Play 1 + Gain/Loss Play 2 + Gain/Loss Play 3 + Gain/Loss Play 4 = Ending yard line
So, for the given plays:
20 + 1 - 8 - 12 + 24 = X
Now, let's solve the equation:
20 + 1 - 8 - 12 + 24 = X
20 - 19 + 24 = X
1 + 24 = X
25 = X
This means the football team will start their next play on the 25-yard line.
