Answer:
9 hours
Step-by-step explanation:
If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.
So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.
In summary she must work 9 hours

Answer:
The area of the pentagon is = 31.5
Step-by-step explanation:
<em>First, we determine the perimeter of the "Pentagon" drawn in the attachment:</em>

<em>Now, we'll check the formula for pentagons:</em>

<em>we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:</em>
apothem=3
<em>then, we can substitute the values in the formula</em>

Let me know if you have questions :D
1/2x + 1/3y = 3
Well, because every answer choice isn't in fraction form, simply multiply EVERYTHING by 6 :)
6(1/2x + 1/3y = 3)
Simplify.
3x + 2y = 18
So, our LAST answer choice is correct.

Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
