To evaluate the expression \(-14.6 - 8.9 + 12.8 + (-12.8)\), we can simplify it step-by-step:
1. Start with the first two numbers:
\[
-14.6 - 8.9 = -23.5
\]
2. Now add \(12.8\) to \(-23.5\):
\[
-23.5 + 12.8 = -10.7
\]
3. Finally, add \(-12.8\) to \(-10.7\):
\[
-10.7 + (-12.8) = -10.7 - 12.8 = -23.5
\]
Thus, the value of the expression is \(-23.5\).
The answer is \( \text{A. } -23.5 \)
1. Start with the first two numbers:
\[
-14.6 - 8.9 = -23.5
\]
2. Now add \(12.8\) to \(-23.5\):
\[
-23.5 + 12.8 = -10.7
\]
3. Finally, add \(-12.8\) to \(-10.7\):
\[
-10.7 + (-12.8) = -10.7 - 12.8 = -23.5
\]
Thus, the value of the expression is \(-23.5\).
The answer is \( \text{A. } -23.5 \)
