\(\frac{x}{0,16}=\frac{9}{x}\Rightarrow x^2=\frac{36}{25}\Rightarrow x=\frac{6}{5}\)hoặc \(x=-\frac{6}{5}\)
\(\frac{x}{0,16}=\frac{9}{x}\Rightarrow x^2=\frac{36}{25}\Rightarrow x=\frac{6}{5}\)hoặc \(x=-\frac{6}{5}\)
x:0.16=9:x
x:0.16=9:x
\(\left(x-1\right):0.16=\left(-9\right):\left(1-x\right)\)
Tìm x biết :
a. x :0.16=9:x
b/ (72-x):7=(x-70):9
c. (X^2-1^2)+(x-y+3)^2=0
4 : x =x : 0.16
tìm x biết : 0.16:x=x:36
\(\left(-3\right)^2\cdot\frac{1}{3}-\sqrt{49}+\left(-5\right):\sqrt{25}\)
\(4\frac{3}{4}+\frac{5}{19}-\frac{3}{4}+1.5+\frac{14}{9}\)
\(\frac{x}{3}=\frac{y}{2}\)và x+y=10
\(\frac{1}{3}-0.84-0.16+\frac{2}{3}+\frac{2}{11}\)
tim x
a) (x - 7/3) : \(2\frac{3}{21}\)+ 3/5 = 0.16
b) (x + 5/6) . \(2\frac{2}{5}\)- \(1\frac{1}{4}\)= 0.35
