Lesson 5 CA Standard 1.0 Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable. Standard 25.1 Students use properties to construct simple, valid arguments (direct and indirect) for, or formulate counterexamples to claimed assertions.

Lesson 5 Ex1 Distribute Over Addition or Subtraction EXERCISE Julia walks 5 days a week. She walks at a fast rate for 7 minutes and then cools down for 2 minutes. Rewrite 5(7 + 2) using the Distributive Property. Evaluate to find the total number of minutes Julia walks. 5 (7 + 2) = 5 ● 7 + 5 ● 2 Distributive Property = 35 + 10 Multiply. = 45 Add. Answer: Julia walks for 45 minutes each week.

She walks to school in 15 minutes and then walks home in 10 minutes. Rewrite 5(15 + 10) using the Distributive Property. Then evaluate to find the total number of minutes Susanne spends walking to and home from school.

Lesson 5 Ex2 The Distributive Property and Mental Math Use the Distributive Property to find 12 ● 82. 12 ● 82 = 12( 80 + 2 ) Think: 82 = 80 + 2 = 12(80) + 12(2) Distributive Property = 960 + 24 Multiply. = 984 Add. Answer: 984

Lesson 5 Ex3 Algebraic Expressions A. Rewrite 12( y + 3) using the Distributive Property. Then simplify. 12 ( y + 3) = 12 ● y + 12 ● 3 Distributive Property Answer: 12 y + 36

Lesson 5 Ex3 Algebraic Expressions B. Rewrite 4( y 2 + 8 y + 2) using the Distributive Property. Then simplify. 4 ( y 2 + 8 y + 2) = 4 ( y 2 )+ 4 (8 y ) + 4 (2) Distributive Property = 4 y 2 + 32 y + 8 Multiply. Answer: 4 y 2 + 32 y + 8 BrainPop: The Distributive Property
