Answer:
30 years old
Step-by-step explanation:
Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.
Simplify the equation.
3x=45, x=15
Joe is 15. Billy is 2(15)=30.

Answer:
8
Step-by-step explanation:
Let x represent the length of the shortest side. Then (x+7) is the length of the longer side, and (3x-7) is the length of the hypotenuse. The Pythagorean theorem gives the relation ...
(3x -7)² = x² +(x +7)²
9x² -42x +49 = x² +x² +14x +49
7x² -56x = 0 . . . . . . . . . subtract the right side, simplify
7x(x -8) = 0
Values of x that satisfy this equation are x=0 and x=8. We know x=0 is not a viable solution, so ...
the shortest side is 8 units long
