Jenni always works three times as many hours as Scott. If Scott works his typical 4 hours
on Monday and twice that amount on Tuesday, how many hours does Jenni work over
the same time period?

** How Can I Use This? **
Mr. Walker and a friend sell candy bars for a fundraiser over a span of three days. Mr.Walker sold the same number of bars each day, but doesnt remember how many candybars he sold. His friend sold four bars every day. How many bars did they sell?

1.2 The Distributive Property
[3]
Steps for the Distributive Property
Multiplying with Variables
Simplify the expression by multiplying the constant with the variable term.
1. (3) (8x) = 2. (2) (x) = 3. (4) (4x) =
1. (6) (3x) = 2. (2) (9x) = 3. (5) (x) =
Distributive Property
Simplify the expression by multiplying both inside terms by the outside
term.
1. 7(2x + 8) = 2. 5(3x + 4) =
3. 3(5x + 2) = 4. 2(4x + 1) =
5. 4(6x + 3) = 6. 6(x + 9) =
1. Determine what the question is asking
2.Multiply the outside number with both of the inside numbers
a. Multiply the outside number with the first term
b. Multiply the outside number with the second term
3. Simplify the expression (if possible)

Guided Practice
Simplify the expression by multiplying both inside terms by the outside
term.
1. 4(x + 3) = 2. 2(3x + 7) =
3. 7(7x + 1) = 4. 5(2x + 6) =
5. 8(5x + 1) = 6. 9(x + 8) =
7. 7(8x + 2) = 8. 4(5x + 7) =
9. 2(6x + 4) = 10. 8(x + 2) =
11. 9(2x + 2) = 12. 5(x + 1) =

Partner Practice
Simplify the expression by multiplying both inside terms bythe outside
term.
1. 9(2x + 4) = 2. 5(6x + 9) =
3. 7(3x + 1) = 4. 8(4x + 5) =
5. 4(5x + 2) = 6. 9(x + 7) =
7. 7(8x + 2) = 8. 3(x + 7) =
9. 2(6x + 7) = 10. 6(5x + 2) =
11. 2(9x + 1) = 12. 5(x + 1) =
