Date: Sect 3.1 Obj: There are two ways to simplify 7(3 + 6) 7(3 + 6) 7(3 + 6) What is the name of this property? Definition: a(b + c) = Ex 1: Simplify 2(x + 4) Are these two expressions equivalent? Let x = 3 Ex 2: Use the distributive property to write an equivalent algebraic expression. a) 3(x + y) b) (y + 3)6 c) 4(x – 2) d) ‐2(n – 3) Read and complete example 2 on page 99. Method 1: Method 2: Ex 3: A uniform costs $42 for the sweater and $29 for the pants. Write 2 equivalent expressions for the total cost for 6 uniforms. Then find the cost. Method 1: Method 2: Ex 4: Deli sandwiches cost $4.95 each. What is the total cost of 8 sandwiches? Use mental math. Another way to think about 4.95 is 5 – 0.5. So 8 * 4.95 can be written as 8( ) Ex 5: Julia commutes to work on the train 4 times each week. A round‐trip ticket costs $7.25. What is her weekly cost for the tickets? Use mental math.
