Answer: The two companies never charge the same amount to rent a bicycle for the same number of hours.
Answer:
x=5/13
Step-by-step explanation:
2/3+7/2=9x+5/6+4x
2/3+7/2-5/6=9x+4x
lcm of 2,3,6=6
2/3=4/6 7/2=21/6 5/6=5/6
4/6+21/6-5/6=9x+4x
30/6=13x
5=13x
x=5/13
- - 9+7=16
And you can do:
10+6=16 aswell. <span />
