Too lazy to format so here
R = 20D =
R = 20(6) =
120 = 20(6)
r = 120 = the days it cost to rent bike
so expensive
Okay, so we multiply..
And we know that a week = 7 days..
So..
2 * 2/3 * 7 = ???
We change the 2 into 2/1
THEN we multiply..
2/1 * 2/3 = 4/3
Then we change the 7 into 1/7.. ( Which is still a whole )
Then multiply again..
4/3 * 1/7 = 4/21
You can correct me if I'm wrong...
I hope this helps you!
So (m+n)/2= 7
To find m+n, multiply both sides by 2
m+n=14
Final answer: C
6... I think.
I hope that this is right
