Answer:
![\frac{7}{x+7}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bx%2B7%7D)
Step-by-step explanation:
<u>Step 1: Pull a 7 from the top</u>
<u />![\frac{7x + 42}{x^2 + 13x + 42}](https://tex.z-dn.net/?f=%5Cfrac%7B7x%20%2B%2042%7D%7Bx%5E2%20%2B%2013x%20%2B%2042%7D)
![\frac{7(x + 6)}{x^2 + 13x + 42}](https://tex.z-dn.net/?f=%5Cfrac%7B7%28x%20%2B%206%29%7D%7Bx%5E2%20%2B%2013x%20%2B%2042%7D)
<u>Step 2: Factor the bottom</u>
<u />![\frac{7(x + 6)}{(x + 7)(x + 6)}](https://tex.z-dn.net/?f=%5Cfrac%7B7%28x%20%2B%206%29%7D%7B%28x%20%2B%207%29%28x%20%2B%206%29%7D)
<u>Step 3: Cancel the top (x+6) and the bottom (x+6)</u>

Answer: ![\frac{7}{x+7}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bx%2B7%7D)
185-7=178
So 178÷185=0.9621621
0.96×100=96%
OR APPROXIMATELY 96 percent
90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...
0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded
what is 30% of 3a.....and we know that "a" is 48.89...
0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer
Well that would be 105 - 10. If you spent 105 minutes in total and 10 of that was putting your stuff away, take that 10 minutes away and you’d get 95. So, she spent 95 minutes washing 3 cars in total. If you divide that 95 into 3s, you get rounded 31 minutes each.
