X= 3
Cancel 3 out by subtracting it by itself, then subtract 3 from 18 to get 15. Now that you have 5x= 15, just divide 15 by 5x to get x= 3

Answer:

22.99

Step-by-step explanation:

Well, $24.99 dollars no matter how many miles. if she drove 200 miles, we will say that x represents miles driven. So, the cost will be $24.99+ $0.10x

to solve, substitute 20 for x.

$24.99 + $0.10(20)

$24.99 + $2

$24.99

$x^\frac{4}{3} x^ \frac{2}{3}$ Lets get started :)

Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.

When multiplication occurs in the same base, we add the powers
$x^\frac{4}{3} x^ \frac{2}{3}$
↓ (I am going to perform the problem separately and then give the final answer as the power to x)
$\frac{4}{3} + \frac{2}{3}$ = $\frac{6}{3} = 2$
↓
x²

$(x^2)^ \frac{1}{3}$

The power of a power should be performed by multiplying the powers together.
2 x $\frac{1}{3}$ = $\frac{2}{3}$

$x^\frac{2}{3}$

Your final answer will be the second option
