To solve \(-30 + 4.5\), we can break it down step-by-step:
- Start with \(-30\).
- Add \(4.5\) to it.
So:
\[ -30 + 4.5 = -25.5 \]
Now, let's check the provided options:
A. \(-30 + 4.5 = -3 + 4.5 = 1.5\) (Incorrect)
B. \(-30 + 4.5 = -1 \cdot 30 + 4.5 = -1 \cdot 1 + 4.5 = -1 + 4.5 = 3.5\) (Incorrect)
C. \(-30 + 4.5 = -3 \cdot 0 + 4.5 = 0 + 4.5 = 4.5\) (Incorrect)
D. \(-30 + 4.5 = (-3)0 + 4.5 = 1 + 4.5 = 5.5\) (Incorrect)
None of the options show the correct process or correct answer for \(-30 + 4.5\). The correct answer is \(-25.5\).
