Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age

x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
There are 11 elements are in (A U B)
<h3>How to determine the number of elements?</h3>
The given parameters are:
n(A) = 4
n(B) = 7
The number of elements in (A U B) is calculated using:
n(A U B) = n(A) +n(B) - n(A U B)
Given that the sets have distincts elements, we have:
n(A U B) = 4 + 7 - 0
Evaluate
n(A U B) = 11
Hence, there are 11 elements are in (A U B)
