The true inequality statements are -5"> − 3 > − 5 , -6"> 2 > − 6 , and -3.5"> − 3 > − 3.5 . The false statements are -3.5"> − 5 > − 3.5 , 2"> − 6 > 2 , and -3"> − 3.5 > − 3 . Understanding these comparisons helps clarify how numbers relate to each other on the number line.

-5, 2>-6, -3>-3.5}"> − 3 > − 5 , 2 > − 6 , − 3 > − 3.5
Explanation
Analyze the problem We need to evaluate each inequality statement to determine which ones are true.
Evaluate each inequality Let's analyze each inequality:
-3.5"> − 5 > − 3.5 is false because -5 is to the left of -3.5 on the number line.
-5"> − 3 > − 5 is true because -3 is to the right of -5 on the number line.
2"> − 6 > 2 is false because -6 is to the left of 2 on the number line.
-6"> 2 > − 6 is true because 2 is to the right of -6 on the number line.
-3"> − 3.5 > − 3 is false because -3.5 is to the left of -3 on the number line.
-3.5"> − 3 > − 3.5 is true because -3 is to the right of -3.5 on the number line.
Identify true statements The true inequality statements are:
-5"> − 3 > − 5
-6"> 2 > − 6
-3.5"> − 3 > − 3.5
Examples
Understanding inequalities is crucial in many real-life situations. For example, when managing a budget, you might use inequalities to ensure that your expenses do not exceed your income. If your income is I and your expenses are E , the inequality E"> I > E ensures you're not overspending. Similarly, in cooking, inequalities help maintain the correct proportions of ingredients. If a recipe calls for at least 2 cups of flour but no more than 3, you can represent this as 2 ≤ flour ≤ 3 . These concepts extend to more complex scenarios, such as optimizing resource allocation or setting safety limits in engineering.
