Chapter 2 Inequalities
In earlier grades, students measured commonly used objects and chose proper units for measurements. Now they will use unit and scale as tools to model and solve problems. Working with units and the relationships between them provides a foundation for the study of expressions, equations,and functions.Students have written and solved linear equations in one variable. Now they extend this work to inequalities. The methods for solving inequalities are very similar to the methods for solving equations; many students strengthen their understanding by studying both. As with equations, students will create and use inequalities to solve problems in contextual situations.
