AgendaWednesday, October 7

1. Correct homework.

2. More equation solving steps.

3. Quiz 2.1 - 2.3 tomorrow 7th period - maybe.

4. World on a grid project work for art field trip days

Homework 16 p. 91 # 15 - 18, 21, 25

p. 84

2.2n - 5 = 7

3.-1 = 3 + 4x

6.x/3 - 9 = 0

p. 84

15.-3 + m/3 = 12

17.double the number of books plus 4028 books is 51,514 books in total

n = number of books

2n + 4028 = 51,514

p. 84

18.18 carrots plus 2 per minute is 60 carrots total

m = number of minutes

2m + 18 = 60

19.one plan at $39.95 plus $.35 per minute is 69.70

m = number of minutes

39.95 + 0.35m = 60.70

p. 84

46.1/2 = 2/5c - 3

47.10.7 = -d + 4.3

p. 91

1.4n - 2n = 18

3.a + 6a - 9 = 30

5.72 + 4 - 14c = 36

p. 91

7.9 = -3 + n + 2n

9.-13 = 2b - b - 10

11. x + x + 9 = 25

Solving Equations- today step 3, 5, 6

Step 1 - Use the Distributive Property to remove parenthesis on EACH side of the equation

Step 2 - Clear the equation of fractions and decimals

mulitply each term by lowest common denominator

Step 3 - Combine Like Terms on EACH side

Step 4 - Use addition or subtraction to put all variable terms on one side of the equation

Step 5 - Undo addition or subtraction

Step 6 - Undo multiplication or division

Now you try -

complete Check Understanding 3 p. 89

a) 3(k + 8) = 21

b) 15 = -3(x - 1) + 9
