Answer:

[tex]w = \frac{70y}{9x} [/tex]

Step-by-step explanation:

[tex] \frac{9x}{10y} = \frac{7}{w} [/tex]

First of all cross multiply

We have

[tex]9xw = 70y[/tex]

Next divide both sides by 9x to make sure that w stands alone

That's.

[tex] \frac{9xw}{9x} = \frac{70y}{9x} [/tex]

We have the final answer as

[tex]w = \frac{70y}{9x} [/tex]

Hope this helps you.
