4. HW#6: Distributive Property Answers

5. 3.) Find three consecutive even numbers with a sum of 72
Warm-Up.
1.) If evaluate 4 – x
2.) Solve for x:
3.) Find three consecutive even numbers with a sum of 72
x = -11
4 – x
4 – (-11) 15
2. Subtract 6 from both sides
Multiply both sides by 7
x = -63
(x) + (x + 2) + (x + 4) = 72
3x + 6 = 72
3x = 66
x = 22
The three consecutive numbers are 22, 24, 26.

SWBAT… solve multi-step equations
Agenda
WU (10 min)
6 examples: multi-step equations
Warm-Up:
1.) Review your quiz
If you got below the mean (74%), your additional HW is to correct the ones you got wrong and turn it in tomorrow. 7

8. Mean = 74%
Range = 30% -100%

9. b = 1 1.) b – 8b + 1 = -6 Solve each equation: List the steps:
1. CLT: b – 8b = -7b
2. Subtract 1 from both sides
3. Divide both sides by -7
b = 1
b = 1

10. m = -12 2.) -(m + 1) = 11 Solve each equation: List the steps:
1. Distribute the -1
2. Add 1 to both sides
3. Divide both sides by -1
m = -12
m = -12

11. g = 14 3.) 5(g + 8) – 7 = 103 Solve each equation: List the steps:
HW#8-Multi-Step Eqns
1. Distribute the 5
2. CLT: 40 – 7 = 33
3. Subtract both sides by 33
4. Divide both sides by 5
g = 14

12. k = 12 4.) Solve each equation: List the steps:
1. Cross multiply 3(k+3) = 9(5)
2. Distribute the 3
3. Subtract both sides by 9
4. Divide both sides by 3
k = 12
k = 12

13. x = 1 5.) Multiply both sides of the equation by 6 (each term)
To remove fractions from an equation:
Multiply both sides of the equation (each term) by the least common multiple (denominator.)

Solve:
1.) ½(12n – 4) = -( n)
1.) n = 1 15

16. x = 40 2.) Solving linear equations involving fractions
Multiply both sides of the equation by 10 (each term)
x = 40
x = 40
To remove fractions from an equation:
Multiply both sides of the equation (each term) by the least common denominator
