A football team gained 6 yards on a first down, lost 15 yards on the second down
liubo4ka [24]

Answer:

7 yards

Step-by-step explanation:

gained 6 yards on a first down   +6

lost 15 yards on the second down   - 15

gained 12 yards on the third down   +12

At the end of the third down

+6 -15+12 = +3

They want to have a 10 yard gain at the end of the 4th down

+3 + x = +10

Subtract 3 from each side

+3-3 +x = +10-3

x = 7

They need to gain 7 yards
