PLEASE HELP WITH A FEW MATH QUESTIONS! 10 POINTS! WOO.?

Answers to the questions wont help you. These people wont be here on your test. So- as a result- you will fail it. I recommend talking to your math teacher for tutoring and that will help you learn it. If you really care about your math grade or learning the stuff- you will go. I am not saying this to be mean- but how can answers with no knowledge on how they got them can help you?
