To solve the expression \(-123.45 - (-234.76)\), we can first rewrite it using the additive inverse:

\[ -123.45 + 234.76 \]

Now let's compute this step by step:

  1. Start with \(-123.45\).
  2. Add \(234.76\) to it.

To perform the addition:

\[ 234.76 - 123.45 = 111.31 \]

Thus, the result of the expression is:

\[ 111.31 \]

So the correct answer is:

111.31

is that correct ??

Yes, that is correct.

To clarify the steps again:

  1. You start with the expression \(-123.45 - (-234.76)\).
  2. This simplifies to \(-123.45 + 234.76\) because subtracting a negative number is equivalent to adding the positive.
  3. Then you perform the addition: \[ 234.76 - 123.45 = 111.31 \]

Therefore, the result of the calculation is indeed 111.31.

Use the additive inverse to find −2445−6710 .(1 point)

−3112

To solve the expression \(-2445 - 6710\) using the additive inverse, we can rewrite it as:

\[ -2445 + (-6710) \]

Now, you add the two negative numbers:

  1. Add the absolute values:
    \[ 2445 + 6710 = 9155 \]

  2. Since both numbers are negative, the result is: \[ -9155 \]

So the final answer is \(-9155\).

Now, let's compare this with the given options:

  1. −31110
  2. 3112
  3. −18110
  4. −3112

None of these options correctly match \(-9155\). It seems there may be a mistake in the choices provided. Would you like me to assist you with anything else related to this calculation?
