Find how many miles he rode for 1 hour, by dividing the distance he rode by the time he rode:
26 miles / 2 hours = 13 miles per hour.
Now divide the distance you want to find the time for by his rate:
104 miles / 13 miles per hour = 8 hours.
The answer is 3c + 4d - 15e
1. apply the distributive property
3(-2c)+3(4d)+3(-5e)+9c-8d
2. simplify
-6c+12d-15e+9c-8d
3. add -6c and 9c
3c+12d-15e-8d
4. subtract 8d from 12d
3c+4d-15e
i hope this helped ! <3
