Answer:
a) x=7/2
Step-by-step explanation:
a) since f(x) is=0, plug in 0 to → f(x)=2x-7 [this f(x)]. you would get 0=2x-7. solve for x by adding 7 and dividing by 2 which you get x=7/2.
X * 0.85 = 136
x = 136/0.85
x = 160
hope this helps :)
Let, the number = x
It would be: x * 0.135 = 57
x = 57 / 0.135
x = 422.23
