Answer: d = 63
Explanation:
d/7 + (-59) = -50
d/7 - 59 = -50
d/7 = -50 + 59
d/7 = 9
d = 9 x 7
d = 63
2/3x=10
3/2 x 2/3x = 3/2 x 10
x=30/2=15
Using Union function of set theory, we get the answer as
A∪B= {3,4,6,8,9,12,15,16,20,21}.
What is Union function?
- The set containing all the elements in a collection of sets is referred to as the union (denoted by ) in set theory. This was one of the core elements that allows sets to be joined together and connected to one another.
- A union of zero A∪B sets is referred to as a nullary union, which is by definition equivalent to the empty set.
- The set containing items in A, B, or both A and B is the union of the two sets A and B.
- In set-builder notation, "displaystyle A" means "∪" and "B" means "x"
- A∪B equals x: x in A's text or x in B's.
Using Union function of set theory, we get the answer as
A∪B= {3,4,6,8,9,12,15,16,20,21}.
