Use an inequality symbol to write each statement. 13 - 3 is less than or equal to 10.

Guida verificata passo dopo passo

Identify the two expressions being compared: the left side is \(13 - 3\) and the right side is \(10\).

Calculate the value of the left side expression: \(13 - 3 = 10\).

Understand the inequality phrase "less than or equal to" corresponds to the symbol \(\leq\).

Write the inequality by placing the left side expression, the inequality symbol, and the right side value: \(13 - 3 \leq 10\).

This inequality states that the value of \(13 - 3\) is either less than or exactly equal to \(10\), which matches the given statement.
