= 1.1959521619135%
Step-by-step explanation:
11 - 10.87/10.87
= 0.13/10.87
= 1.1959521619135%
54 because if x+y=82 and x-y=26 add 26 and 82 is 108 the divide it by 2 your answer is 54
X = 3/2 or 1 1/2
Both of the equations equal -10, therefor the equations are equal.
Ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.
90/4 = 22.5....so each of them pay 22.50 each for the flat rate.
so John's equation is : 22.5 + 0.25x = 147.50
5≤x≤9 it can also be reversed as 9≥x≥5 which is the same thing
