Question

1. -13.9 + \frac{p}{12.8} = -13.306

Explanation:

Step1: Rewrite the equation

The equation is \(-13.9+\frac{p}{12.8}=-13.306\). First, add \(13.9\) to both sides of the equation to isolate the term with \(p\).
\(\frac{p}{12.8}=-13.306 + 13.9\)

Step2: Calculate the right - hand side

Calculate \(-13.306+13.9\). \(13.9 - 13.306=0.594\), so \(\frac{p}{12.8}=0.594\).

Step3: Solve for \(p\)

Multiply both sides of the equation \(\frac{p}{12.8}=0.594\) by \(12.8\) to solve for \(p\).
\(p = 0.594\times12.8\)

Step4: Calculate the product

Calculate \(0.594\times12.8\). \(0.594\times12.8=(0.6 - 0.006)\times12.8=0.6\times12.8-0.006\times12.8 = 7.68-0.0768 = 7.6032\)

Answer:

\(p = 7.6032\)
