To determine which expression for \( A \) makes the equation \( A = 5 - \) true, we can analyze each option given. The equation suggests that \( A \) needs to equal \( 5 \) minus some value (which is currently undefined since we have a blank after the minus sign).
-
\( A + \): This doesn't specify a numeric value and does not form a complete expression.
-
\( A = 1 + \): This suggests \( A \) is equal to \( 1 \) plus something else, which does not directly lead to \( A = 5 - \).
-
\( A = 1 \): This assigns \( A \) a value of \( 1\). If we substitute that into the equation, \( 1 \) cannot equal \( 5 - \) since we do not have a defined value for the right-hand side.
-
\( A - 1 + \): This means \( A \) takes on a value that is one less than something else, which again does not define \( A \) directly and does not relate to the target of 5.
None of the proposed options clearly define \( A \) in such a way that it equals \( 5 - \) as the expressions are either incomplete or do not yield a specific result. If we assume you meant to complete "5 - " with a certain value, the only clearly relatable equation to reach 5 from the choices would be \( A = 5 \).
Among your options, the most fitting expression to make \( A = 5 - \) true would be \( A = 1 + 4 \) if rephrased, as that gives us 5 explicitly, but it's not clearly in the options provided.
If only one option must be chosen based on the immediate similarity to mathematical notation, \( A = 1 + \) may imply \( A \) could be larger than 1, leaning toward 5 depending on what follows the \( + \).
