I think you want the fraction 11/15. or as a percentage 11 is 73.33 % of 15.
-3x+6/8x-9 is the correct response ( I believe )
2/3 and 3/2 cancels out, which leaves:
b=12/21
b=4/7
To evaluate this expression you just have to substitue the value that is given.
so since we know m=2 x=7 y=5
and the expression is given mx-y
plug these values in as 2(7)-5 = 14-5 = 9
the answer is C $40
Just add up all the numbers and pick the choice closest to what you get
