Hello,
In a Venn 's diagram: A={Custumer edu},B={french}, U=the class.
#(A\B)=22-2=20
#(B\A)=20-2=18
#(A∩B)=2
#U=80
p=(20+2+18)/80=20/40=1/2
Answer C (11/40+1/4-1/10=20/40=1/2)
Sorry for the mistake.
Answer: Required expression : 
Smallest number = 27
Step-by-step explanation:
Let the three consecutive number be n-1 , n , n+1 .
Since , the sum of three consecutive numbers is 84.

Remove parenthesis

Simplify

Divide both sides by 3, we get

That means the three consecutive numbers would be (28-1) , 28 , (28+1)
i.e. 27 , 28 , 29.
Hence, the smallest number is 27.

Answer:
x=4
Step-by-step explanation:
2/3 x + 5/6 = x - 1/2
Multiply each side by 6 to clear the fractions
6(2/3 x + 5/6) = 6(x - 1/2)
Distribute
4x +5 = 6x-3
Subtract 4x from each side
4x+5 -4x = 6x-3-4x
5 = 2x-3
Add 3 to each side
5+3= 2x-3+3
8 =2x
Divide by 2
8/2 =2x/2
4 =x
