ban oi, day la trang hoc toan ma, ban ko nen hoi tieng anh . Nhung mk chi gop y thoi nhe, chuc ban hoc tot.
Áp dung tính chất của DTSBN,ta có :
\(\frac{y}{x-z}=\frac{x+y}{z}=\frac{x}{y}=\frac{x+y}{x+y-z}\)(1)
=>\(\frac{x+y}{z}=\frac{x+y}{x+y-z}\)=>z=x+y-z =>2z = x + y
Thay vào (1) =>\(\frac{2z}{z}=\frac{x}{y}\)=> \(2=\frac{x}{y}\)=>y=2x (ĐPCM)
(2x+3)\(^2\) = \(\frac{25}{9}\)
=> 2x+3 = \(\frac{5}{3}\)
=> 2x = \(\frac{5}{3}\) - 3
=> 2x = \(-\frac{4}{3}\)
=> x =\(-\frac{2}{3}\)
TH2: (2x+3)\(^2\) =\(\frac{29}{5}\)
=> 2x+3 = \(-\frac{5}{3}\)
=> 2x = \(-\frac{5}{3}\) - 3
=> 2x = \(-\frac{14}{3}\)
=> x = \(-\frac{7}{3}\)
gợi ý nhé
xyz=4900 (=) 70xyz=343000 (=) 2x*7y*5z=343000
áp dụng giả thiết đề bài =) 8x3=343000 =) x=35
=) 7y =70 (=) y=10
=) 5z = 70 (=) z= 14
vậy ...
chúc bn hc tốt
