we know that s=12 is part of the solution. Use the second equation to find the value of f.

Question

0.75f+0.5s=9
f=16−s

s=12
f=16−s
f=

Answer 1

To find the value of \( f \) using the second equation \( f = 16 - s \) and substituting \( s = 12 \):

\[ f = 16 - s \] \[ f = 16 - 12 \] \[ f = 4 \]

So, the value of \( f \) is \( 4 \).
