Jason and Hilger are required to paint over the graffiti on a wall. If Jason worked alone, it
would take him 20 h to repaint. Working alone, Hilger could do the job in
15 h. How long
will it take them to do the painting if they work together?

8.57

Step-by-step ex

60t cross out 60 it turns in to 3t and 4t

3t+4t=60

7t=60

t==8.57rs

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
