If 28% of a sum is $100.80, what is the sum?
Answers
Call the sum S. Then, you can use the definition of percentage to obtain an equation to find the value of S: 1) 28% = 28 / 100; 2) 28% of x = (28/100)x; 3) that is equal to $100.80 => (28/100)x = 100.8 => x = 100.8 * 100 / 28 => x = 360. You can verify that the 28% of 360 is 100.80: 360 * 28/100 = 100.80. Then, the answer is $360.

Answers
If you would like to find the coefficient of the variable in the expression 6 - 4x - 8 + 2, you can calculate this using the following step:
6 - 4x - 8 + 2 = 6 - 8 + 2 - 4x = - 4x
The correct result would be - 4.
Answer:
The coefficient is -4

What is the simplified form of the expression square root of 1/144?
Answers
1/12
When simplifying a radical, pull out any perfect squares. In this case it works out nicely. 1 is the square of 1 and 144 is the square of 12, so you get 1/12.
In another case such as sqrt(20) you can pull out a 4 which is a perfect square which leaves 5. So the answer would be 2sqrt(5).
