1. Warm Up October 31, 2011 What is the main goal in a football game? What is the main goal in a basketball game? What is the main goal in a baseball game?

2. Warm Up October 27, 2011 What is the main goal in a football game? TO SCORE A TOUCHDOWN What is the main goal in a basketball game? TO MAKE A FIELD GOAL What is the main goal in a baseball game? TO SCORE A RUN

3. To score a touchdown, field goal, or run, all players must follow the… RULES!

4. Solving Equations Just like in a game of sports… there’s a goal there are rules Solve for n n – 8 = 20 + 8 +8 n = 28 Solve for n n ÷ 7 = 8 *7 * 7 n = 56 You are writing invitations to a party. It takes your four minutes to complete each invitations. Write an equation for finding n, the number of invitations you can complete in one hour. 4n = 60 ÷4 ÷ 4 n = 15 invitations

5. Solving Equations Solve for n 3n – 8 = 19 2n + 3 = 13 Solve for n n – 8 = 20 + 8 +8 n = 28 Solve for n n ÷ 7 = 8 *7 * 7 n = 56

6. Solving Equations Solve for n 3n – 8 = 19 +8 +8 3n = 27 ÷3 ÷3 n = 9 Check 3(9) – 8 = 19 27 – 8 = 19 19 = 19

7. Solving Equations Solve for n 2n + 3 = 13 -3 -3 2n = 10 ÷2 ÷2 n = 5 Check 2(5) + 3 = 13 10 + 3 = 13 13 = 13

8. Solving Equations Solve for n n ÷ 3 + 17 = 32 -17 -17 n ÷ 3 = 15 x 3 x 3 n = 45 Check 45 ÷ 3 +17 =32 15 + 17 =32 32=32

9. Which process is done first? 5n + 7 = 23 ÷ 5 ÷ 5 5n + 7 = 22 - 7 - 7 5n = 15 ÷ 5 ÷ 5 n = 3

10. Solve the following equations. 2n + 1 = 73y – 4 = 2

11. Solve the following equations. c ÷ 3 - 7 = 5.332 = n ÷ 3 + 17

12. Write an equation to solve… You pay $35 in dues to a photo club and $10 per roll you have developed. If you spend $225 during the year, how many rolls of film do you have developed? 10n + 35 = 225
