Answer:

x = 30

Step-by-step explanation:

well from the theorem we have

\frac{15}{3}=\frac{x}{6}

yes i know you could say that the right way is

\frac{3}{15}=\frac{6}{x}

well if you notice they are the same only that in my way the x is in the numerator which means it will be far easier to know it's value :)

so

\frac{15}{3}=\frac{x}{6}\\\\5=\frac{x}{6}\\\\6[5]=6[\frac{x}{6}]\\\\30=x

What value of r makes the equation true? r 0.12 = 0.20 A. r = 0.32 B. r = 0.08 C. r = –0.08 D. r = –0.32
muminat
Depends on your question...

If your question is r + 0.12 = 0.20 then do this:

Subtract 0.12 from both sides

r = 0.08

The answer is B.


If your question is r - 0.12 = 0.20 then do this:

Add 0.12 on both sides

r = 0.32

The answer is A

So it depends on your question :P
