Agenda Wednesday, October 7 1.  Correct homework. 2.  More equation solving steps. 3.  Quiz 2.1 - 2.3 tomorrow 7 th  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
