The answer to this is 50 x 10 the 9th power.
Hope this helps :)
Half of 9 1/4 is 4 5/8 or 37/8
8-4x-7=5x+30-2
combine like terms
1-4x=5x+28
-27=9x
divide both sides by nine
-3=x
(5,5), (-5,5) is a function. To be a function x
cannot be repeated.
Matthew charges $25 for each haircut, and earned $325
Divide 325 with 25
325/25 = 13
