The table shows the amount earned for washing cars. How much is earned for washing 25 cars? 3 cars=$13.50, 6 cars=$27, 9 cars=$4
katrin2010 [14]
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

2 1/4 - 2/3. A. 1 3/7. B. 1 7/12. C 2 3/7. D 2 11/12
DedPeter [7]

Answer:

B.) 1\frac{7}{12}

Step-by-step explanation:

2\frac{1}{4} -\frac{2}{3} Then multiply 4 by 2, then add 1.frac{9}{4} - \frac{2}{3} \\

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

\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}

to get: \frac{27}{12} - \frac{8}{12}.

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: \frac{19}{12} = 1\frac{7}{12}.

Your final answer is 1\frac{7}{12}[/tex].
