Answer 1

To solve \(-30 + 4.5\), let's break it down correctly.

1. \(-30\) can be rewritten as \(-3 \times 10\) (which doesn't actually help in this case).
2. The calculation itself comes down to combining the negative number with the positive one.

To find the correct approach:

- Start with \(-30\).
- Add \(4.5\) to it.

So, the calculation is straightforward:

\[
-30 + 4.5 = -25.5
\]

Now, looking at the provided responses, all the options mix up steps and show incorrect calculations. However, the direct answer is:

\(-30 + 4.5 = -25.5\)

None of the provided options correctly depict the accurate process for this specific equation.

If I had to select an answer from the given options that was closest, it would be:

\(-30 + 4.5 = -3 \cdot 0 + 4.5 = 0 + 4.5 = 4.5\)

However, that process is incorrect because \(-30\) doesn't simplify to \(-3 \cdot 0\) or anything close to that.

So, in summary, there isn't a correctly represented solution for \(-30 + 4.5\) in your options. The actual answer, as computed traditionally, is \(-25.5\).
