If 100% of a number is 15, then what is 50% of the number?

Answer:
7.5
Step-by-step explanation:
One way in which you could do this problem would be to write and solve an equation of ratios:
100% 15
--------- = ----------
50% x
Cross multipying results in 100x = 750, so that x = 7.5.
50% of the number is 7.5.
Answer:
The answer is 7.5.
Step-by-step explanation:
Since we're looking for half of 15, divide 15 by 2 (or multiply 15 by 0.5, it's the same thing) and you get 7.5.
I hope this helped! :)

Answer: 11 - (-12) = <em><u>
23</u></em></h2>

-22 - 49 = <u><em>
-71</em></u></h2>
When you factor the equation...
r^2-4r-77
r^2+7r-11r-77
r(r+7)-11(r+7)
(r-11)(r+7) so each parenthetical term is a dimension.
Note that r>11 though for any possible real solution.
