700

700 is the answer

Answer 2

Step-by-step explanation:

[\frac{-3}{7} + \frac{4}{5}] + \frac{-5}{9} = \frac{4}{5} + [\frac{-3}{7} + \frac{-5}{9}][

We know that the associative property of addition is a + (b + c) = (a + b) + c.

\begin{gathered}[\frac{-3}{7} + \frac{4}{5}] + \frac{-5}{9}\\\\= \frac{-3}{7} + \frac{4}{5} + \frac{-5}{9}\\\\= \frac{4}{5} + \frac{-3}{7} + \frac{-5}{9}\\\\= \frac{4}{5} + [\frac{-3}{7} + \frac{-5}{9}]\end{gathered}
