Set up an equation
1/2x+6=2/3x
Take all x's to one side & constants to other
1/2x-2/3x=-6
Subtract by getting a common denominator
-1/6x=-6
Divide both sides by -1/6
x=36
Answer:
![n(A)=38](https://tex.z-dn.net/?f=n%28A%29%3D38)
Step-by-step explanation:
In sets theory n(A) represents the number of elements in set A.This number is the cardinal number of the set A.
For n(AUB) there is an equation that relates n(A),n(B) and n(A∩B) :
n(AUB) = n(A) + n(B) - n(A∩B)
In our exercise :
n(AUB) = n(A) + n(B) - n(A∩B)
![59 = n(A) +38-17\\n(A) = 59-38+17\\\\n(A)= 38](https://tex.z-dn.net/?f=59%20%3D%20n%28A%29%20%2B38-17%5C%5Cn%28A%29%20%3D%2059-38%2B17%5C%5C%5C%5Cn%28A%29%3D%2038)
Another important equation for maths is similar to this one :
P(AUB) = P(A) + P(B) - P(A∩B)
Where ''P'' is the event probability.This equation is used in probability and statistics.
I believe it's A. Day 1 decreased by half from 8 would be 4. Day 2 decreased by half from 4 would be 2. Day 3 decreased by half from 2 would be 1. then .5 would be decrease by. 25, which would be .75. I hope that makes sense:)
