Question 14

The expression evaluates to 13 when x=11.

To find the value of the expression x + 44 / (2x) when x is 11, we substitute 11 into the expression and simplify: 11 + 44 / (2 * 11) = 11 + 44 / 22 = 11 + 2 = 13.

A) 33

Option A is incorrect because substituting x = 11 into the expression does not yield 33. The calculations show that the correct evaluation leads to a result of 13 instead.

B) 2.5

Option B is incorrect as substituting x = 11 into the expression results in a value much higher than 2.5. The expression simplifies to 13, which clearly does not match this option.

C) 13

Option C is correct because substituting x = 11 into the expression yields 11 + 44 / (2 * 11) = 11 + 2 = 13, aligning perfectly with the calculated result.

D) 55/22

Option D is incorrect since while 55/22 simplifies to 2.5, it does not reflect the evaluated expression when x = 11. The correct evaluation leads to 13, which is not represented by this option.

Conclusion

The evaluation of the expression confirms that when x = 11, the result is 13, which is accurately reflected in Option C. Other options either misinterpret the calculation or provide incorrect values, reinforcing that C is the only correct choice.
