Answer:
7 hours
Step-by-step explanation:
basically the fine for using the bike is 8 dollahs then 3 dollahs per hour the bike is used so the equation will look like this. h equals hours
3h+8=29
solve like any other equation
subtract 8 from both sides. 3h+8-8=29-8
rewrite the equation 3h=21 now isolate the variable divide by 3 from both sides of the equation
3h/3=21/3
rewrite the equation h=7
he rode for 7 hours
