If \(x=5\), what is the value of \(\frac{x+3}{2}\)?
Answer and explanation
Correct answer: 4
Given \(x=5\), substitute it into the expression: \(\frac{x+3}{2}=\frac{5+3}{2}=\frac{8}{2}=4\). Therefore, the correct answer is 4. The value 8 is only the numerator \(x+3\); it must still be divided by 2. Exam tip: After substitution, simplify step by step and pay attention to the order of operations.
