BELL WORK X - 7 = -1 X - 4 = 66 8 = X - 2 -8 = X - 2 X = 6 X = 70 X = 10 X = -6

MODELING THE EQUATION USING A BAR DIAGRAM

253 Competitors

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

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

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

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

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. ? New book Used book 17 9 X – 9 = 17 X = \$26 for a new book

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

USE THE MODEL TO WRITE AND SOLVE AN EQUATION X + 4 = 7 X = 3

USE THE MODEL TO WRITE AND SOLVE AN EQUATION X + 2 = 6 X = 4
