Answers:
1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.
1D. I just did
Well think of it like this. lets say your teacher made you do this problem -48 - 10. I would just act like 48 is not an negative and add 10. After that I would put the negative back. So the answer would be -58. :P

Just look for the smallest number out of the three and then the smallest out of the two left, like 10,2,20. 2, 10, 20
.9x-2.1+.9=.2(5-x) multiply .2(5-x)
.9x-2.1+.9=1-.2x; add - 2.1 + .9
.9x-1.2=1-.2x; cancel -2x by adding it by itself and add it on the .9x
1.1x-1.2=1; cancel -1.2 by adding it by itself and add it on the 1
1.1x=2.2; divide 1.1 so it can be canceled and then on 2.2
x=2 :)
