a = 250

b = 10

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Step-by-step explanation:

Step 1: Define

$a=\frac{5x^2}{2}$

$b=\frac{2x^2(x-5)}{10x}$

x = 10

Step 2: Evaluate

Substitute in x: $a=\frac{5(10)^2}{2}$ Exponents: $a=\frac{5(100)}{2}$ Multiply: $a=\frac{500}{2}$ Divide: a=250

Substitute in x: $b=\frac{2(10)^2(10-5)}{10(10)}$ Exponents: $b=\frac{2(100)(10-5)}{10(10)}$ Subtract: $b=\frac{2(100)(5)}{10(10)}$ Multiply: $b=\frac{1000}{100}$ Divide: b=10

0.0125x or x/80

Step-by-step explanation:

Salary: x dollars per year

To find the pay per month, we divide the annual pay by 12.

The monthly pay is x/12

15% of the first month's salary is

15% of x/12 = 0.15 * x/12 = 0.0125x = x/80

0.0125x
