X=30.4-2y
(step by step) :
It cost $156.40 because 20% of 195.50 is $39.10 so you subtract that from the 195.50.
Answer:
n = 2
Step-by-step explanation:
1.2n - 1.5 = 0.45n
collect like terms
1.2n - 0.45n = 1.5
0.75n = 1.5
divide both side by 0.75
0.75n/0.75 = 1.5/0.75
n =2
7/x = 84 / (156 -x)
84x = 7(156 -x)
84x = 1092 - 7x
91x = 1092
x = 12
AC = 156 - 12 = 144
