A.−30+4.5=−3+4.5=1.5

B.−30+4.5=−1⋅30+4.5=−1⋅1+4.5=−1+4.5=3.5

C.−30+4.5=−3⋅0+4.5=0+4.5=4.5

D.−30+4.5=(−3)0+4.5=1+4.5=5.5

Answer 1

To solve \(-30 + 4.5\), we can break it down step-by-step:

1. Start with \(-30\).
2. 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 \(-25.5\).
