Inequality Constraint or Condition Word Problems Worksheets
What Is an Inequality Constraint or Condition? Comparing numbers is a concept that is an important one since it will help students in solving complex equations in higher classes. The major part of learning inequality is to understand the concept of inequality constraints. There are four types of inequality constraints, namely less than (<), greater than (>), less than and equal (≤), and greater than and equal (≥). Just like its name, it helps us to understand the value of the unknown variable. Let us take an example. Charlotte Bobcats, on their first NBA game, scored 84 points and lost the match. On the other hand, on their second game of the season, they again scored 84 points and won the game. So, what was the difference between the two games? Charlotte Bobcats vs. Houston Rockets = 84 points to 87 points; 84 < 87 Charlotte Bobcats vs. Toronto Raptors = 84 points to 79 points ; 84 > 79 Here, we can see that Bobcats scored 84 points in both games; however, their opponents scored different points in both games. Therefore, we have used inequalities to display the point difference between both teams in both games. These worksheets and lessons will help students understand the constraints and conditions under which an inequality can be accepted.
