Answer:
5%
Step-by-step explanation:
so basically we know in 3 years she spent 390 dollars
so 390 divided by 3 is 130
so all we need to do is find this:
130 is what percent of 2600
so the final answer is 5%
Answer:
x=5
Step-by-step explanation:
23-3= 4x or 20
that means 4x is equal to 20
20 divided by 4 is 5
so x is equal to 5
F(x) = 2x² - x
f(3) = 2(3)² - 3
f(3) = 2(9) - 3
f(3) = 18 - 3
f(3) = 15
f(x) = 2x² - x
f(5) = 2(5)² - 5
f(5) = 2(25) - 5
f(5) = 50 - 5
f(5) = 45
The answer is C.
