It takes 8 hours for one crew to clean an office building. It takes a second crew 10 hours to clean the same building. If the first crew works 2 hours and leaves and the second crew takes over to complete the job, how long will it take the second crew to...

1/3+2/9x=1 2/9x=2/3 x=3 hours

1/8-1 hour 2/8- 2 hours 2/8+1/10x=1 1/10x=6/8 x=7.5 hrs

1. 1/6+1/4x=1 1/4x=5/6 x=20/6 hrs= 3 2/6 hrs

you fill t with 0 so 0-2-1=-3 if it said find g(t)=6 1/6-2-1=-17/6
