Answer
\[
\begin{array}{r}
18.8 + (-7.5) = 11.3 \\
7.9 - 49.35 = -41.45
\end{array}
\]
Solution
Let's compute each expression step by step:
\[
\begin{array}{r}
18.8 + (-7.5) = 18.8 - 7.5 = 11.3 \\
7.9 - 49.35 = 7.9 + (-49.35) = -41.45
\end{array}
\]
**Final Answers:**
\[
\begin{array}{r}
18.8 + (-7.5) = 11.3 \\
7.9 - 49.35 = -41.45
\end{array}
\]

Simplify this solution Beyond the Answer
To solve the computations, let's break them down step by step. For the first equation: \[ 18.8 + (-7.5) \] This is equivalent to: \[ 18.8 - 7.5 \] Performing the subtraction: \[ 18.8 - 7.5 = 11.3 \] So, \[ 18.8 + (-7.5) = 11.3 \] Now for the second equation: \[ 7.9 - 49.35 \] Since 49.35 is larger than 7.9, the result will be negative. Performing the subtraction: First, convert 7.9 to a decimal with two decimal places: \[ 7.9 = 7.90 \] Now subtract: \[ 7.90 - 49.35 = -41.45 \] So, \[ 7.9 - 49.35 = -41.45 \] Putting it all together, we have: \[ \begin{array}{r} 18.8+(-7.5)=11.3 \\ 7.9-49.35=-41.45 \end{array} \]
