Answer:
46 housewives read all three magazines.
Step-by-step explanation:
Given:
n(A) = 150
n(B) = 200
n(C) = 156
n(A∩B) = 48
n(B∩C) = 60
n(A∩C) = 52
n(A∪B∪C) = 300
so we know the relation as:
n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)
∴ n(A∩B∩C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) - n(A∪B∪C)
= 150 + 200+ 156 - 48 - 60 - 52 - 300
= 46
Hence the number of housewives that had read all three magazine is 46.

8x - 20
Step-by-step explanation:
3(x - 6) + 4 + 5x - 6 Distribute 3 to (x - 6)
3(x) - 3(6) + 4 + 5x - 6
3x - 18 + 4 + 5x - 6
Simplify:
3x + 5x - 18 + 4 - 6
8x -18 - 2
8x - 20
