[tex]\frac{5}{6} =\frac{10}{x}

12

Step-by-step explanation:

I think you are trying to say .

If that's the case, you can multiply the left side by 2/2:

10/12 = 10/x

Then, since the numerators are the same and the denominator of one side is 12, the denominator of the other side must also be 12. Therefore, x = 12.

I hope this helped.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
