2.  It is the numerical factor that contains a variable.  In other words, it is a number in a math sentence that has a letter right by it.

3. The coefficient is next to a variable because it shows/tells how many times to multiply the variable.

4.  Variable - an unknown number represented by a letter.  Term - mathematical expression.  Expression - a mathematical phrase that combines numbers and/or variables using mathematical operations.

5.  6x: 6 is the coefficient of x; 6x-->6 times x.  The letter x is a variable.

6. w = 5; v = 3 8w - 2v = 8(5) - 2(3)

7. Replace w with 5 and v with 3. 8 X 5 - 2 X 3 = 8(5) - 2(3)

8. Do all multiplications first. 8 X 5 - 2 X 3 = 8(5) - 2(3) = 40-6 =

9. Subtract 6 from 40. 40 – 6 = 34
