MODELING THE EQUATION USING A BAR DIAGRAM
253 Competitors
Use the model to write and solve an equationX + 134 = 253
or 134 + x = 253
X = 119 boys
Use the model to write and solve an equationX – 15 = 119
X = 134 girls
Use the model to write and solve an equationX + 15 = 134
X = 119 boys
Use the model to write and solve an equationX + 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
