which is M = 9pn solved for p?

p = M/9n

To solve the equation M = 9pn for p, we need to isolate the variable p on one side of the equation. Let's start by dividing both sides by 9n:

M = 9pn

Dividing both sides by 9n:

M / (9n) = pn

Now, we can rearrange the equation to solve for p. To do this, we'll switch the order of the terms on the right side:

p = M / (9n)

Therefore, the equation M = 9pn, when solved for p, is p = M / (9n).
