NO EXPLANATION IS NEEDED! WILL MARK BRAINLIEST IF YOU GET IT RIGHT! 7TH GRADE MATH PEOPLE, DO NOT ANSWER THIS WRONG PLEASE!!! (sorry for the caps, wanted to catch attention)

Anyways so the problem that I am having trouble with is in the file that is attached to this question. Please answer it correctly.
I need these answers by midnight EDT and well I am really in a pickle right now since I can not find the answers. I also am having trouble with two other questions so if you want the extra points go on my profile and check out my last question where I had two of these for quite a bit of points.
ANSWER ALL PARTS OF THIS QUESTION, if you do not the whole thing gets marked wrong.
