Answer:
-25
Step-by-step explanation:
Substitute r = 2 in the equation.
-9(2) - 7 = -18 - 7 = -25
Phone B
4
First n(AUB)=n(E) - n((AUB)')
So n(AUB) = 40 - 6 = 34
Now all u hv to do is use the formulae,
n(AUB) = n(A) + n(B) - n(ANB)
So when u substitute above values,
34=22 + n(B) - 8
So,
n(B) = 4
b
25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
