Answer 3

To solve the expression \( -12 - (-6) \), we can rewrite it:

\[
-12 + 6
\]

Now, we perform the addition:

\[
-12 + 6 = -6
\]

So, the value of \( -12 - (-6) \) is \(-6\).

The correct response is:

**-6**

Answer 4

To solve the expression \( -18.1 + 5 \), we can perform the addition:

\[
-18.1 + 5 = -18.1 + 5.0
\]

To add, we can think of it in terms of moving on the number line. Starting at \(-18.1\) and moving \(5\) units to the right:

\[
-18.1 + 5 = -13.1
\]

Thus, the value of \( -18.1 + 5 \) is \(-13.1\).

The correct response is:

**-13.1**

Answer 5

To calculate the value of \( -189.987 - 30.87 \), we perform the operation:

\[
-189.987 - 30.87 = -189.987 - 30.870
\]

When you add two negative numbers, you combine their absolute values:

\[
= - (189.987 + 30.87)
\]

Now, let's calculate \( 189.987 + 30.87 \):

\[
189.987 + 30.87 = 220.857
\]

Therefore,

\[
-189.987 - 30.87 = -220.857
\]

So, the value of \( -189.987 - 30.87 \) is \( -220.857 \).

The correct response is:

**-220.857**
