Answer:
84
Step-by-step explanation:

One yard is 3 feet.
2(3) = 6, so he gained 6 feet on the first play. Therefore, the first play had the greater gain.
3(x-4)=2x+7 the answer is going to be x-19
Brown marker- 3/8 because there are 3 brown out of a total 8.
Yellow crayon- 2/8 = 1/4 because there are 2 yellow out of a total 8. If we simplify that and divide 2 from both sides, we get 1/4. :) Hope that helps! <3
