To find how many square feet Stefanie can paint in one hour, divide the number of square feet by the fraction of an hour: 12 2/3 divided by 2/5 = 38/3 divided by 2/5. =31 2/3
4x - 1/3 = 7/1
+1/3 +1/3
_______________
4x = 7.3 (repeating)
(divide each side by 4)
x = 7.3 (repeating) / 4

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
