2 hours, 29-17 equals 12 12/6 equals 2

Answer:

2 hours.

Step-by-step explanation:

x= number of hours

y= total cost in $

y=6x+17

Since she paid 29 dollars, we plug it into y which gives us

29=6x+17  

Then, solve for x.

29-17=6x+17-17

12=6x

(12/6)=(6x)/6

2=x

Therefore, Norachai rented the bike for 2 hours.
