Question

10)
\frac{n - 12.9}{6.1} = -0.377

Explanation:

Step1: Start with the given equation

We have the equation \(\frac{n - 12.9}{10}=- 0.377\)

Step2: Multiply both sides by 10

To eliminate the denominator on the left - hand side, we multiply both sides of the equation by 10.
\(10\times\frac{n - 12.9}{10}=10\times(-0.377)\)
Simplifying the left - hand side (the 10 in the numerator and denominator cancels out) and the right - hand side, we get:
\(n-12.9=-3.77\)

Step3: Add 12.9 to both sides

To solve for \(n\), we add 12.9 to both sides of the equation.
\(n-12.9 + 12.9=-3.77+12.9\)
Simplifying the left - hand side (the \(- 12.9\) and \(+12.9\) cancel out) and calculating the right - hand side:
\(n = 9.13\)

Answer:

\(n = 9.13\)
