N - 2 / - 3 = - 6 (1) multiply both sides by -3 to get n - 2 alone
n - 2 = 18 (2) add 2 to both sides; 2 on left side gets cancelled so we can now have n all alone
n = 20
Answer:
7/8
Step-by-step explanation:
To find: number which represents the expression
Solution:
Integers refers to natural numbers, 0 together with negative of rational numbers.
A rational number is the number of the form where p and q are integers and .
So, represents
Total population of US is 234.88 million.
Step-by-step explanation:
Given,
Number of people are 65 or older = 30.3 million
This represents 12.9% of total population.
Let,
x represent the total population.
12.9% of x = 30.3 million
Dividing both sides by 0.129x
Total population of US is 234.88 million.

2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer
