-9f = -99 f =

To solve the equation \(-9f = -99\), you can divide both sides by -9:

\[ f = \frac{-99}{-9} \]

This simplifies to:

\[ f = 11 \]

So, \(f = 11\).

972 = p + 518
p =

To solve the equation \(972 = p + 518\), you can isolate \(p\) by subtracting 518 from both sides:

\[ p = 972 - 518 \]

Now, perform the subtraction:

\[ p = 454 \]

So, \(p = 454\).

2f = 7.2
f =

To solve the equation \(2f = 7.2\), you can divide both sides by 2:

\[ f = \frac{7.2}{2} \]

Now, calculate the division:

\[ f = 3.6 \]

So, \(f = 3.6\).
