Description

"Organization and Review" Equation PPT Courseware

teaching objectives

1. Go through the process of systematically reviewing, consolidating and improving the knowledge of equations and solving equations.

2. Further master the method of solving equations using the properties of equations, and be able to use equations to correctly answer practical problems.

3. In the process of formulating equations to solve problems, we can further understand the function of equations and enhance students' confidence in equations.

Review and consolidate

1. Look at the equations in the diagram and solve them.

Solution: x+5.3=6.2

x+5.3-5.3＝6.2-5.3

x=0.9

2. Make equations to solve problems and check them.

(1) A wild goose flies approximately 1,420 meters per minute, which is 80 meters less than three times the meters a bat flies per minute. How many meters does a bat fly per minute?

Solution: Let the bat fly x meters per minute.

3x-80=1420

3x＝1420＋80

3x=1500

x=500

Answer: Bats fly 500 meters per minute.

(2) Teacher Li brought 1,000 yuan to buy basketballs. After buying 4 basketballs, the remaining money was enough to buy 2 footballs. How much does a football cost?

Solution: Suppose the price of a football is x yuan.

2x＋140×4＝1000

2x+560＝1000

2x=1000-560

2x=440

x=220

Answer: The price of a football is 220 yuan.

Consolidate application

1. Connect each equation below to its solution.

2. Solve the equation.

7x＋24＝45 3.5＋2x＝12

5.8x＋9.2x＝72 25x＋35＝460

3. Make equations and solve them.

4. The area of ​​a triangular land is 780 square meters. Its height is 30 meters, and how many meters is its base?
