Consider sets r, s, and t, defined as follows: r = { x ϵ z | x is divisible by 2 }s = { y ϵ z | y is divisible by 3 }t = { z ϵ z | z is divisible by 6 }a) is r ⊆ t? explain. b) is t ⊆ r? explain. c) is t ⊆ s? explain.

a) No b)Yes c) No

Step-by-step explanation:

a) No, R is not a subset of T that is NOT ALL the elements of R can be found in T. For R ⊆ T, it means that ALL the element of R can be found in T which is false in this case.

b) Yes, T is a subset of R that is ALL the element of T can be found in T since all the elements in both sets are all even. For T ⊆ R, it means that ALL the element of T can be found in R

c) No, T is not a subset of S that is NOT ALL the elements of T can be found in S. For T ⊆ S, it means that ALL the element of T can be found in S which is false in this case.

false

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
