@dc104

Answer 1

4 = 5/9*x
4/(5/9) = x
36/5 = x

Answer 2

x=36/5

Answer 3

You have to use cross multiplication

4(9) = 5x

Are you with me so far?

36 = 5x

36/5 = x

Answer 4

\[\frac{ 4 }{ x } = \frac{ 5 }{ 9 }\]
cross-multiply
\[4(9) = x(5) \rightarrow 36 = 5x \rightarrow x = 7.2\]

Answer 9

I am not looking for a simplified. I am sorry @StudyGurl14 . I am the one who was wrong here.
My textbook said 36/5, it didn't show the simplified version.

Answer 10

It's fine @Geniu
