Answer:
the total cost would be $45.2
Answer:
x = 2
Step-by-step explanation:
(16 =
and 8 =
)

Since the base number is 2, the exponents must equal each other.
So:
12x = 3x+18
9x = 18
x = 2
First of all, you want the variable to be isolated, so in order to do that, you divide in both sides. Ten divided by two is five. So f = 5.
2f + 10
--- ---
2 2
10 divided by 2 = 5
3(x-9)
when you distribute the equation you get
3(x)-3(9) which is the last answer
It would be be because they didn’t distribute the 8n to the 20
