Transcript text: Solve the following formula for the specified variable.
\[
\begin{array}{l}
A=\frac{1}{2} g \cdot n \text { for } g \\
g=\frac{2 a}{n}
\end{array}
\]
Solution
Solution Steps
To solve the formula \( A = \frac{1}{2} g \cdot n \) for \( g \), we need to isolate \( g \) on one side of the equation. We can do this by multiplying both sides by 2 and then dividing by \( n \).
Step 1: Isolate \( g \)
Starting with the equation:
\[
A = \frac{1}{2} g \cdot n
\]
we multiply both sides by 2:
\[
2A = g \cdot n
\]
Next, we divide both sides by \( n \) to isolate \( g \):
\[
g = \frac{2A}{n}
\]
Step 2: Substitute Values
Given \( A = 10 \) and \( n = 5 \), we substitute these values into the equation:
\[
g = \frac{2 \cdot 10}{5}
\]
Step 3: Calculate \( g \)
Now, we perform the calculation:
\[
g = \frac{20}{5} = 4.0
\]
Final Answer
Thus, the value of \( g \) is
\[
\boxed{g = 4.0}
\]
