rate = (47 2/3 km)/(4 1/3 hrs) = (143/3)/(13/3) = 143/13 = 11 km/hr
We will use the FOIL method to solve this.
(7x-7)(x+1)
Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

Now, we need to simplify by combining like terms.

If you look, -7x and 7x are gone. This is because they cancel each other out.
I hope this helped and maybe consider giving me brainliest :)
Answer
27 - R = C
if she rented 16 of them then
27 - 16 = C And C = 11
If you add 28 3/4 and 15 1/4 that is half way around The court that is 44m
So all the way around would be 44m×2= 88m
And he went around twice so 88m×2=176m
7/3 written as a mixed fraction is 2 1/3
So
7/3 = 2 1/3
