1. Do Now (Complete @ least 3…Remember to check!) 1.) a – 1.1 = 2.32.) 4.6 = r – 3.2 3.) 7.8 = x + 1.5 4.) a + 6.1 = 8.4 1.) a = 3.4 2.) 7.8 = r 3.) 6.3 = x 4.) a = 2.3

2. 1/8/15 6-2 B Solve & Write Multiplication Equations

3. What’s the goal of solving equations? Goal= to get the variable on 1 side of the =

4. Equations are similar to what? A balanced scale! raggedclothcafe.com

5. coefficient- the number by which the variable is multiplied by 3x=12 What is the variable multiplied by? 3 is the coefficient

6. Ex. 1: Solve 3x = 12 Step 1: Write the equation Step 2: Get the variable by itself using the inverse operation Step 3: Solve for the variable Step 4: Then check!! x = 4

7. Check 3x = 12 3 4 = 12 12 = 12

8. Ex. 2 Solve 2x = 10 Step 1: Write the equation Step 2: Get the variable by itself using the inverse operation Step 3: Solve for the variable Step 4: Then check!! x = 5

9. Check 2x = 10 2 5 = 10 10 = 10

10. Identify the equation that does not have the same value for variable as the other three. Explain. 2x = 129a = 54 8x = 486x = 30

11. Ex. 3: Solve & check your solution 0.4p = 52 0.4 p = 130 Then check! 0.4(130) = 52 52 = 52

12. Ex. 4: Solve & check your solution 0.18t = 0.009 0.18 0.18 t = 0.05 Then check! 0.18(0.05) = 0.009 0.009 = 0.009

13. Ex. 5: Solve & check Then check!

14. Ex. 5 You use 4 ½ cups of flour to make 3 batches of banana chocolate chip bread. How many cups of flour are needed to make one loaf?

15. Write the equation. Divide each side by 3. Multiply by the reciprocal. Simplify.

16. Exit Ticket: Solve each equation & check. 1) 2a = 6 2) 3) 20 = 4c 4) 1.71 = 0.9d 5) Dallas Seavey finished the 2014 Iditarod Race in about 8 ½ days. The “Southern Route” that was taken last year is about 1000 miles. If Seavey traveled at a constant rate, how many miles did he travel per day? Round to the nearest tenth. http://iditarod.com/race/2014/ 1) a = 3 2) f = 2/5 3) 5 = c 4) 1.9 = d 5) Seavey would have traveled 117.6 miles per day.
