HELP!

anonymous · Answer

I am not sure if I understand the question right. Anyway, plug $x=-2$ in the equation, you get $\frac{40}{-2+7.5}=\frac{40}{5.5}=\frac{80}{11}$.

The problem you can get if you write an equation using verbal expressions is that if the equation looks like: $$40/(x) +7.5$$
Then by plugging in you would get the answer:
$$40/(-2) +7.5 = -12.5$$

The way you worded the equation it could go either way...as AnwarA or I stated. Next time try writing the equation exactly how it is given.

how do we calculate 10 +x divided by 40+ x multiplied by 60%?

anonymous · Answer

That would be 15% because the x's cancel and you are left with 1/4 which is 25%. Then it's 25% times 60% which is .25 times .6. This results in .15 or 15%.
