Equation Form:
w x 2 19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.
12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9
You have to find a common denominator 1st then add. So 16 is the common denominator the problem should be 2 7/16+1 14/16+8-16= 3 29/16 then you need to divide 29/16 you will have 4 13/16
