Answer:
Alright, for question 7, the angle pair relationship is that they are corresponding angles.
So, 17x - 34 = 13x - 14. This means that 4x = 20, and x = 5 :)
For question 8, the angles are a linear pair. They are supplementary (adding to 180) :)
So, 37x - 17 + 33x - 13 = 180
This means taht 4x = 210, and x = 52.5? (I'm not sure if I screwed up on the arithmetic on this one, please correct if you find any mistakes!)
48.0858.
First you multiply 44.94 and .07 (the decimal equivalent of 7%) which gives you 3.1458. You take 3.1458 and add it to 44.94 (since it's an additional fee) and that gives you 48.0858
