SOLUTION: For sets A and B, determine whether A = B, A is a subset of B, or B is a subset of A A = {x| x &#1108; N and 13 < x < 20} B = {14, 15, 16, 17, 18}

Question 191917: For sets A and B, determine whether A = B, A is a subset of B, or B is a subset of A

A = {x| x є N and 13 < x < 20}
B = {14, 15, 16, 17, 18}

A = { x| x ? N and 13 < x < 18}
B = { 12, 13, 14, 15, 16, 17, 18}
Did I do this problem correctly? If not, can someone help me do it correctly? I appreciate it!

You can put this solution on YOUR website!
A={x|x eN and 13< x < 20} ----> A = {14,15,16,17,18,19}

All of B is in A ----> B is a subset of A

A is not subset of B since 19 e A but 19 is not in B

---> A does not equal B


Answer: B is a subset of A (all other possibilities are false)
