Answer:
55
Step-by-step explanation:
75+50=125
180-125=55
First, you have to find what 80% of 15 is. In order to do that you have to change 80% percent to decimal, which would be .80. Then, multiply .80 and 15 to get 12. Subtract 12 from 15 and your answer is 3.
distribute the 8 to the 5 and x. then distribute 11 to 9 and x.
(40+8x)=(99+11x)
-11x -11x
-3x+40=99
-40 -40
-3x= 59
divide three on both sides
x=59/-3
final answer x=-59/3
