Description
Targeted practice for NC.6.EE.8: Reason about one-variable inequalities by: using substitution to determine whether a given number in a specified set makes an inequality true; writing an inequality of the form x > c or x < c to represent a constraint or condition; recognizing that inequalities have infinitely many solutions; representing solutions of inequalities on number line diagrams. Each problem gives immediate feedback with the full worked solution. Ungraded practice toward proficiency.

### Practice: Reason About Inequalities
Reason about one-variable inequalities by: using substitution to determine whether a given number in a specified set makes an inequality true; writing an inequality of the form x > c or x < c to represent a constraint or condition; recognizing that inequalities have infinitely many solutions; representing solutions of inequalities on number line diagrams.
Work each problem. If you get it right, you will see a check and can move on. If you get it wrong, you will see exactly why and the steps to the correct answer, then you can try the next one. This practice is not graded.
