You need to find out how much it costs to wash one car, so:
3×=13.50
Divide both sides by 3.
x=4.5 per car.
Now multiply 4.5 by 25 which should give you $112.50
Answer:
x+13
Step-by-step explanation:
5x+2(3-2x)+7
5x+6-4x+7 <em>open</em><em>ing</em><em> </em><em>brac</em><em>ket</em><em>.</em><em>.</em><em>.</em>
<em>now </em><em>collect</em><em> </em><em>like</em><em> </em><em>terms</em><em>.</em><em>.</em><em>.</em>
5x-4x+6+7
x+13
Answer:
x = 12
Step-by-step explanation:
set up a proportion:
<u> 24 </u> = <u> 32 </u>
33 32+x
24(32 + x) = 32(33)
768 + 24x = 1056
24x = 288
x = 12
Answer:
B.) 
Step-by-step explanation:

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

to get:
.
now the denominators is the same on both sides, just subtract the numerator.
27 - 8 = 19
Now simply:
.
Your final answer is 1\frac{7}{12}[/tex].
