To solve the expression \(-5.45 + 4.12 - 8.66\), we can follow these steps:
-
First, calculate \(-5.45 + 4.12\): \[ -5.45 + 4.12 = -1.33 \]
-
Next, subtract \(8.66\) from \(-1.33\): \[ -1.33 - 8.66 = -10.00 \]
Now we'll compare the result and check the provided options: The calculation shows: \(-10.00\) does not seem listed as an option, so let's carefully double-check the calculations:
-
Calculate \(-5.45 + 4.12\) accurately: \[ -5.45 + 4.12 = -1.33 , (correct) \]
-
Now subtract \(8.66\) from \(-1.33\): \[ -1.33 - 8.66 = -10.00 \]
None of the provided choices seem to match our result. However, the calculations are correctly pointing to \(-10\) which isn’t listed in the options provided.
Based on numbers provided in the multiple choice, let's re-evaluate against given values. If there's a problem with provided choices, we collated it correctly.
Conclusively:
- The answer to the expression \(-5.45 + 4.12 - 8.66\) is \(-10.00\).
If asked to choose within misaligned options, none are truly correct; revisit possible transcription.
Thus the confirmed value here is indeed: \(\mathbf{-10.00}\) or misconsidering or outside options mismatching which weren't aligned in presented format. Ponder reconciling discrepancies if essential in formative dialogues with those supplied within.
