Question 122495: I need help with the following
For sets A and B, determine whether A = B, A is a subset of B, of B is a subset of A:
A = {x| x є N and 13 < x < 18}
B = {12, 13, 14, 15, 16, 17, 18}
Answer by Fombitz(32388)   (Show Source):
You can put this solution on YOUR website! When you look at the definition of A, it includes all natural numbers greater than 13 and less than 18 or,
A={14,15,16,17}
Comparing this to set B, it looks like set A is a subset of set B,
because all of the elements in set A are contained in set B.
