Expectations Try all 24 classwork problems (2 pts) Make sure you have the correct answers on your classwork before you leave (2 pts) Preview homework to see if you know how to complete it (2 pts) Raise your hand if you have a question (2 pts) Stay in seat and stay quiet when instructor is giving the lesson (2pts)

  2. Distributing Meet JT At JT’s birthday party, he has the responsibility to pass out cake to all his friends

  3. Some friends are inside the house Some friends are in the yard

  4. No matter where they are, Atta boy, JT 3 pieces!!! everyone gets cake

  5. 6 friends are in the house 5 friends are in the yard

  6. ( + )

  7. 3(6 + 5) =

  8. 3(6 + 5) = 18 + 15 = 33 pieces of cake

  9. Suppose JT didn’t know how many were outside

  10. The expression would look like this: 3(6 + x) =18 + 3x

  11. 3(2x + 1)= 6x+ 3

  12. –2(3x + 2)= -6x - 4

  13. Distributinganswers 6x + 3 -6x - 4 -8x + 12 -2x -1 -12 + 8m 2/3x + 1/3

  14. Distributing among parenthesis AND combining like terms 2(n – 5) + 4 = 2n – 10 + 4 2n – 6 Now, combine like terms

  15. Distributing among parenthesis AND combining like terms 8(x – 2) – 7x= 8x – 16 – 7x x – 16 Now, combine like terms

  16. Distributing among parenthesis AND combining like termsanswers 2n - 6 x - 16 -2n - 9 6x - 6 -2x + 6 -3g + 15

  17. Combining like terms AND moving constant to the other side of the equal sign Combine like terms 8x – 2 – 7x = -9 X – 2 = -9 Add the opposite of the constant to both sides +2 +2 X = -7

  18. Combining like terms AND moving constant to the other side of the equal sign Combine like terms –5x – 12 + x = 13 -4x – 12 = 13 Add the opposite of the constant to both sides +12 +12 -4x = 25 x = -25/4

  19. Combining like terms AND moving constant to the other side of the equal signanswers -7 -25/4 -1/2 -4/7 -1 3/4

  20. Equations with fractionsRule: Multiply each co-efficient by its inverse Find the co-efficient –3x = 3 4 -1 - 1 3 3 Find the inverse of the co-efficient x = -1/4

  21. Equations with fractionsRule: Multiply each co-efficient by its inverse Find the co-efficient 1 x = 6 2 2 2 1 1 Find the inverse of the co-efficient x = 6 x 2 x = 12

  22. Equations with fractionsRule: Multiply each co-efficient by its inverseanswers ¼ 12 8 7 ½ -1/32 8/9
