Question

simplify the expression.
3.5n + 7 - 2.5n
3.5n + 7 - 2.5n = \square
(use the operation symbols in the math p

Explanation:

Step1: Combine like terms (3.5n and -2.5n)

To simplify the expression \(3.5n + 7 - 2.5n\), we first combine the terms with the variable \(n\). The like terms are \(3.5n\) and \(-2.5n\). When we combine these, we subtract their coefficients: \(3.5 - 2.5 = 1\). So, \(3.5n - 2.5n = (3.5 - 2.5)n = 1n\) or simply \(n\).

Step2: Write the simplified expression

After combining the like terms, we still have the constant term \(7\). So, putting it all together, the simplified expression is \(n + 7\).

Answer:

\(n + 7\)
