First simplify:
15h/5h becomes 3 (because 15h & 5h are divisible by 5h)
3+10h/5h+25/5h=x+y+5/h
10h/5h becomes 2 (because 10h & 5h are divisible by 5h)
3+2+25/5h=x+y+5/h
25/5h becomes 5/h (because 25 & 5 are divisible by 5)
3+2+5/h=x+y+5/h
Add 3+2=5
5+5/h=x+y+5/h
subtract -5/h from both sides, which cancel's each one out.
5=x+y
Now depending on whether you are solving for x or y, subtract the opposite, leaving the one you are solving for left by itself, as the one you subtract will cancel itself out on the right side.
5-y=x or x=5-y
or
5-x=y or y=5-x
The answer is B to the problem. B/c difference is 7 on the number line.
<span>We know that
there is no universal acceptance meaning of a percentile. When someone told you
that you are in the 80th percentile, the meaning of that is you
have achieved the lowest score that is greater than 80 percent of the score. It is calculated by using the formula <span>R = P/100 x (N + 1)</span></span>
149 x .47 = 70.03
149 + 70.03 = 219.03
Answer: 219.03
Hope this helped! :)
Its your opinion, or conclusion based on evidence.
not quite a guess, cuz you have a backing.
