1. The problem shows four inequalities involving variables A, B, C, and D with given numbers: - $A \leq 16.5$ - $B < 75$ - $C \geq 74.25$ - $D > 23$ 2. These inequalities express constraints or conditions on the values of A, B, C, and D. 3. To understand or solve problems involving inequalities, remember: - $\leq$ means "less than or equal to". - $<$ means "less than". - $\geq$ means "greater than or equal to". - $>$ means "greater than". 4. Each inequality restricts the possible values the variable can take: - $A$ can be any number up to and including 16.5. - $B$ can be any number strictly less than 75. - $C$ can be any number 74.25 or greater. - $D$ can be any number strictly greater than 23. 5. No further simplification or calculation is needed unless a specific question is asked about these inequalities. Final answer: The inequalities define the ranges for A, B, C, and D as stated above.
