Đổi: 50% = 1/2; 20% = 1/5
Vì 1/2 số thứ nhất là 1/3 số thứ 2 bằng 1/5 số thứ 3 -> Coi số thứ nhất là 2 phần, số thứ 2 là 3 phần, số thứ 3 là 5 phần thì tổng 3 số là 10 phần (vì 2 + 3 + 5 = 10)
Số thứ nhất là: 345 ; 10 * 2 = 69
Đáp số: 69
\(\frac{x+1}{2010}+\frac{x+3}{2008}+\frac{x+4}{2007}+\frac{x+9}{2002}=-4\)
\(\Leftrightarrow\frac{x+1}{2010}+1+\frac{x+3}{2008}+1+\frac{x+4}{2007}+1+\frac{x+9}{2002}+1=-4+4\)
\(\Leftrightarrow\frac{x+2011}{2010}+\frac{x+2011}{2008}+\frac{x+2011}{2007}+\frac{x+2011}{2002}=0\)
\(\Leftrightarrow\left(x+2011\right)\left(\frac{1}{2010}+\frac{1}{2008}+\frac{1}{2007}+\frac{1}{2002}\right)=0\)
\(\Leftrightarrow x+2011=0\)
\(\Leftrightarrow x=-2011\)
a, \(ĐPCM:\hept{\begin{cases}\sqrt{x}-2\ne0\\3-\sqrt{x}\ne0\\x\ge0\end{cases}}\Leftrightarrow\hept{\begin{cases}x\ne4\\x\ne9\\x\ge0\end{cases}}\)
\(Q=\frac{2\sqrt{x}-9}{x-5\sqrt{x}+6}-\frac{\sqrt{x}+3}{\sqrt{x}-2}-\frac{2\sqrt{x}+1}{3-\sqrt{x}}\)
\(=\frac{2\sqrt{x}-9}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}-\frac{\left(\sqrt{x}+3\right)\left(\sqrt{x}-3\right)}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}+\frac{\left(\sqrt{x}-2\right)\left(2\sqrt{x}+1\right)}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}\)
\(=\frac{2\sqrt{x}-9-x+9+2x-3\sqrt{x}-2}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}\)
\(=\frac{x-\sqrt{x}-2}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}\)
\(=\frac{\left(\sqrt{x}+1\right)\left(\sqrt{x}-2\right)}{\left(\sqrt{x}-2\right)\left(\sqrt{x}-3\right)}=\frac{\sqrt{x}+1}{\sqrt{x}-3}\)
