Presentation Transcript

  1. Bell Work • X = 6 • X = 70 • X = 10 • X = -6 • X - 7 = -1 • X - 4 = 66 • 8 = X - 2 • -8 = X - 2

  2. Modeling the equation using a bar diagram

  3. 253 Competitors

  4. Use the model to write and solve an equation X + 134 = 253 or 134 + x = 253 X = 119 boys

  5. Use the model to write and solve an equation X – 15 = 119 X = 134 girls

  6. Use the model to write and solve an equation X + 15 = 134 X = 119 boys

  7. Use the model to write and solve an equation X + 119 = 134 X = 15 more girls

  8. A used book costs $17 less than the same book new. The used book costs $9. Use a bar diagram to write and solve an equation to find out how much the new book cost. ? X – 9 = 17 New book Used book X = $26 for a new book 9 17

  9. Use a bar diagram to write and solve an equation to find out how many hits he got in the second game. . X – 1 = 5 X = 4 hits in the second game

  10. Use the model to write and solve an equation X + 4 = 7 X = 3

  11. Use the model to write and solve an equation X + 2 = 6 X = 4
