Answer:
n(A) = 5 + 7 =12
n(B) = 7 + 3 = 10
n(A n B) = 7
n(A u B) = n(A) + n(B) - n(A n B)
5 + 3 - 7 = 1
n(A')=3
n(B')=5

Answer:
He used to receive $14.50.
Step-by-step explanation:
Let x = amount he used to receive.
Now he receives 2x - 4.
Now he receives $25.
2x - 4 = 25
2x = 29
x = 14.5
Answer: He used to receive $14.50.
Answer:
Therefore,

Step-by-step explanation:
Let Assume Some Diameter of a Circle, to Solve it
Diameter = d = 14 inch ( say )
C =Circumference
Pi =constant = 3.14
To Find:
C = ?
Solution:
Formula for Circumference of a Circle is given as

Where,
C = Circumference
d = Diameter
Now Substitute d = 14 inches we get

This way we can find the circumference for any 'd' i.e Diameter
Therefore,

Answer:
<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>
Step-by-step explanation:
Given the expression
- 2 (x + 3) = - 10
The first step in solving the expression is to multiply both sides by -1/2 as shown;
-1/2(-2)(x+3) = -1/2(-10)
(x +3) = 1/2(10)
x + 3 = 5
x = 5-3
x = 2
Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
