  3. The Distributive Property ALGEBRA 1 LESSON 1-7 Use the Distributive Property to simplify 26(98). 26(98) = 26(100 – 2) Rewrite 98 as 100 – 2. = 26(100) – 26(2) Use the Distributive Property. = 2600 – 52Simplify. = 2548 1-7

  4. = 52 – 0.04Simplify. = 51.96 The Distributive Property ALGEBRA 1 LESSON 1-7 Find the total cost of 4 CDs that cost $12.99 each. 4(12.99) = 4(13 – 0.01) Rewrite 12.99 as 13 – 0.01. = 4(13) – 4(0.01) Use the Distributive Property. The total cost of 4 CDs is $51.96. 1-7

  5. The Distributive Property ALGEBRA 1 LESSON 1-7 Simplify 3(4m – 7). 3(4m – 7) = 3(4m) – 3(7) Use the Distributive Property. = 12m – 21 Simplify. 1-7

  6. The Distributive Property ALGEBRA 1 LESSON 1-7 Simplify –(5q – 6). –(5q – 6) = –1(5q – 6) Rewrite the expression using –1. = –1(5q) – 1(–6) Use the Distributive Property. = –5q + 6 Simplify. 1-7
