Step-by-step explanation:
Let be the set of people who like cats and
the set of people who like dogs. Under the cardinality theorem you have
n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the ∩
, you have n
∩
= n(C) + n(D) -
∪

Answer:
x=24
Step-by-step explanation:
The Quotient(dividing) of a number(x) and 6 minus(-) 3 IS(=) 1.
Which turns into:
- 3 = 1
We want to get x by itself so we divide the entire equation by 6.
6 ( - 3 = 1 )
x - 18 = 6
We want to move the plain numbers to one side so x can be by itself. So we add 18 to both sides.
x = 24
