Answer: To make n the subject of the formula n+p/pt = 5p, we can follow these steps:
Explanation:
1. Multiply both sides of the equation by pt to eliminate the fraction: npt + p = 5pt^2
2. Subtract p from both sides of the equation: npt = 5pt^2 - p
3. Divide both sides of the equation by pt: n = (5pt^2 - p) / pt
Therefore, n = (5pt^2 - p) / pt is the formula with n as the subject.
