Capitolo 1, Problema 89
Simplify each inequality if needed. Then determine whether the statement is true or false. 7 ≤ 7
Guida verificata passo dopo passo1
Identify the inequality given: \(7 \leq 7\).
Recall that the symbol \(\leq\) means "less than or equal to," so the statement says "7 is less than or equal to 7."
Since both sides of the inequality are equal, the "equal to" part of the inequality holds true.
Therefore, the inequality \(7 \leq 7\) is true because 7 is indeed equal to 7.
No further simplification is needed as the inequality is already in its simplest form.

Inequality Symbols and Their Meaning
Inequality symbols like ≤ (less than or equal to) compare two values to show their relative size. The symbol ≤ means the left side is either less than or exactly equal to the right side. Understanding these symbols is essential to interpret and solve inequalities correctly.

Evaluating Inequalities
To determine if an inequality is true or false, substitute the values and check the relationship. For example, 7 ≤ 7 means 7 is less than or equal to 7, which is true because both sides are equal. This evaluation step confirms the validity of the inequality.

Simplification of Inequalities
Simplifying inequalities involves reducing expressions to their simplest form without changing their truth value. In this case, the inequality 7 ≤ 7 is already simplified, so no further steps are needed before evaluating its truthfulness.
