Transcript text: Simplify the following linear expression: \[ 0.8+(-2 m)-1.2+6.5 m \]

Solution

Solution Steps

To simplify the given linear expression, we need to combine like terms. Specifically, we will combine the constant terms and the terms involving the variable \( m \).

Step 1: Combine Constant Terms

Combine the constant terms in the expression: \[ 0.8 - 1.2 = -0.4 \]

Step 2: Combine Variable Terms

Combine the terms involving the variable \( m \): \[ -2m + 6.5m = 4.5m \]

Final Answer

The simplified expression is: \[ \boxed{-0.4 + 4.5m} \]
