The expression 50 + 53 - 80 simplifies to 23. None of the provided choices match this result, so the correct answer is 'None of the above'.
The original question given is an algebraic expression:
50 + 53 - 80 = 0
We need to find the expression equivalent to the above.
To simplify the expression, combine like terms:
50 + 53 = 103, so:
103 - 80 = 23
The equivalent expression is therefore 23, which is not one of the given options.
Based on the information provided in the snippets, none of the options (A. 52 + 7, B. 32.11, C. 52.7, D. 32 + 11) match the correct answer of 23, so the answer is: E. None of the above.
The probable question may be:
