Final answer:
The expression 55 has a value greater than 43. It is clearly greater because it is a number already more than 43, and no operations reduce its value.
Step-by-step explanation:
The question asks which expression has a value greater than 43. Looking at the given examples, we see that the operations performed in 55 and 43.4151 both result in numbers greater than 43. Specifically, 55 is already a number greater than 43 without any additional operations. Also, since 43.4151 has a decimal part, it indicates a number that is greater than 43. On the other hand, operations like 23 + 11 only yield 34, which is less than 43.
Another way to look at it is by using the mathematical property stated: If a is more than b, and b is more than c, then a is more than c. Applying this logical sequence to the given expressions would also conclude that 55 (being a) is definitely more than 43 (being c).
Therefore, the expression 55 has a value greater than 43.
