Step-by-step explanation:

$\qquad\sf {:}\longrightarrow m+\dfrac {1}{m}=3$

$\qquad\sf {:}\longrightarrow m^2+1/m=3$

$\qquad\sf {:}\longrightarrow m^2+1=3m$

$\qquad\sf {:}\longrightarrow m^2-3m+1=0$

41%

Step-by-step explanation:

The change in fish count = 850-500=350

The percent decrease when a fish count goes down from 850 to 500 is given by :-

$\text{Percent decrease}=\frac{\text{Change in fish count}}{\text{Previous fish count}}\times100\\\\\Rightarrow\text{Percent decrease}=\frac{350}{850}\times100\\\\\Rightarrow\text{Percent decrease}=41.176470588\%\approx41\%$

Hence, the approximate percent decrease when a fish count goes down from 850 to 500= 41%
