Let's simplify the expression step by step.
The expression is:
\[
-9(0.3m + 0.7) + 2(0.7m + 0.5)
\]
1. Distribute \(-9\) and \(2\):
\[
-9 \cdot 0.3m - 9 \cdot 0.7 + 2 \cdot 0.7m + 2 \cdot 0.5
\]
This simplifies to:
\[
-2.7m - 6.3 + 1.4m + 1
\]
2. Combine like terms:
- Combine the \(m\) terms: \(-2.7m + 1.4m = -1.3m\)
- Combine the constant terms: \(-6.3 + 1 = -5.3\)
So, the simplified expression is:
\[
-1.3m - 5.3
\]
