Difference between subset and proper subset
To answer this question, I will use the following illustration.
In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.
Set C is a subset of A because 
Using the above illustration, we have:
and
is a subset of , because 5 and 8 are in but 2 which ca be found in is not in
They are spaced about 0.030 miles apart or 53.33 yards apart. Just divide 1 mile by 33 and get your answer. :) Hope I helped!
Sum of two sides always greater than the third side
If c is the smallest number, then
5 + c > 7
c > 2
If c is the largest number, then
5+7>c
12>c
Adding c>2 and 12>c, you get 12>c>2 for the answer
