If you are currently assigning or practicing these problems, let me know how I can help: joint and combined variation worksheet kuta

"varies directly as (x) and inversely as (z)".

( y ) varies jointly with ( x ) and ( z ). If ( y = 30 ) when ( x = 2 ) and ( z = 5 ), find ( y ) when ( x = 3 ) and ( z = 4 ). Since it’s combined variation, start with: Step 2:

Substituting $C = 40000$, $n = 80$, and $w = 10$ into the equation, we get $40000 = k \frac80100$. Solving for $k$, we have $40000 = 0.8k$, so $k = 50000$.
