I don't know what you are talking about please re word the question its really hard to understand what your asking.
The answer is 2 .
simplify log(down)10 (1/100) : -2
apply log rule : -log(down)10 (100)
rewrite 100 in power-base form : -log(down)10 (10^2)
apply log rule again : -2log(down)10 (10)
apply one more time : -2*1
Multiply : -2
refine from -(-2) = 2
I hope this helps
Answer:
x = 9
Step-by-step explanation:
(3x-20)/9 = 56/72
72(3x-20) = 9(56)
216x-1440 = 504
add 1440 to each side
216x = 1944
divide both sides by 216
x = 9
