Answer 3

and 6? lol

Answer 4

wait number one too!

Answer 5

ahhhh, I need help on all of these

Answer 6

I hate inequalities. Gr.

Answer 7

I think I can do six. Try to think as the inequality symbol as an equal sign - but don't forget its more than. So now...

-4x + 15 = 59

So, basically you have to subtract 15 from 59 which is 44. So, now divide 44 by -4 which is -11. So x = -11, so it would be C, x <11, because it is less than 11.
