Answer:
7 hours
Step-by-step explanation:
We have that the value of the review of a bicycle has the following function:
v = 14 + 9 * t
where t is the time in hours
if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:
77 = 14 + 9 * t
solving for t:
t = (77 - 14) / 9
t = 7
that is to say that Sara left the bicycle in a total of 7 hours

Answer:
Step-by-step explanation:
Let the numbers be x and y. Then we got following equations:
- x + y = 34
- 1/2x + 1/3y = 14
<u>Double the second equation and subtract from the first one. Solve for y:</u>
- x + y - x - 2/3y = 34 - 2*14
- 1/3y = 6
- y = 3*6
- y = 18
<u>Find x:</u>
