Let $a$, $b$, $c$, $u$, $v$, and $w$ be real numbers satisfying the three equations:
\begin{align*}
  17u +  bv +  cw &= 0 \\
   au + 29v +  cw &= 0 \\
   au +  bv + 56w &= 0.
\end{align*}
Suppose that $ a \ne 17$ and $ u \ne 0$. What is the value of
\[ \frac{a}{a - 17} + \frac{b}{b - 29} + \frac{c}{c - 56} \, ?\]
