117, just add the two and subtract from 180
The answer should be D since after 5 am to 7 am only two hours have passed so x=2, and then you plug in the x as 2 and solve it. You might get not around answer like 39.785 but when you round it, it would be 40.
14*15 is 210 which his the entire area. now divide 210/20 you get 10.5 so you will need at least 11 bags
I dunno if im correct, but for A. I’d say 1/4 for B. I’d say 1 1/2 for C. 2/3
