1.) Set up an equation
50+80h=310 h stands for hours
-50 - 50
80h= 260
divide 80 to both sides
h=3.25
The mechanic works for 3 hours and 25 minutes
Hope this helps explain what was needed to be solved! :)
Step-by-step explanation:
the roots are complex
the answer is in the image above
= h(5 -5) +f(6 +1)
= 7f . . . . . . . . . . . h terms cancel
