18+11v=w-13t
18+11-w=-13t
13t=w-11v-18
t=1/13w - 11/13v - 1 5/13
Hope this helps :)
C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.
The answer is 5. 25^1/2 is the same thing as the square root of 25. The square root of 25 is positive 5 or negative 5 because
5 x 5 = 25 and -5 x -5 = 25.
<u>x + 5y = 4v</u>
Subtract 5y from each
side of your equation: <em> x = 4v - 5y</em>
