  • 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
