Question

1. \frac{1}{2}m + 4 - 1 + 3.5m

Explanation:

Step1: Identify like terms

Like terms for \( m \): \( \frac{1}{2}m \) and \( 3.5m \); like terms for constants: \( 4 \) and \( -1 \).
\( \frac{1}{2}m + 3.5m + 4 - 1 \)

Step2: Convert \( \frac{1}{2}m \) to decimal

\( \frac{1}{2}m = 0.5m \), so \( 0.5m + 3.5m + 4 - 1 \)

Step3: Combine like terms for \( m \)

\( (0.5 + 3.5)m + (4 - 1) \)
\( 4m + 3 \)

Answer:

\( 4m + 3 \)
