Answer
When \( w = -1 \), the expression \( 8.3 + w \) equals 7.3.
Solution
Calculate or simplify the expression \( 8.3+w \).
Simplify the expression by following steps:
- step0: Solution:
\(8.3+w\)
The expression \(8.3 + w\) is equal to \(8.3 + (-1)\).
Substitute \(w = -1\) into the expression:
\[8.3 + (-1) = 8.3 - 1 = 7.3\]
Therefore, the value of the expression when \(w = -1\) is 7.3.

Simplify this solution Bonus Knowledge
When you have the expression \(8.3 + w\) and substitute \(w = -1\), just plug in the value of \(w\). So, it becomes \(8.3 + (-1)\), which simplifies to \(8.3 - 1\). Just like that, you get \(7.3\). This simple process of substituting variables can be found in many areas of mathematics, especially in algebra and even in real-world scenarios. For example, you might use similar expressions in budgeting, where you substitute different values for expenses to see how they affect your total. It’s all about adjusting values and finding out what works best!
