Tim x biet,\(\frac{0,\left(3\right)+0,\left(384615\right)+\frac{3}{13}\chi}{0,0(3)+13}=\frac{50}{85}\)
\(\frac{0,\left(3\right)+0,\left(384615\right)+\frac{3}{13}x}{0,0\left(3\right)+13}=\frac{50}{85}\)
Tìm x biết:\(\frac{0,\left(3\right)+0,\left(384615\right)+\frac{3}{13}.x}{0,0\left(3\right)+13=\frac{50}{85}}\)
\(\frac{0.\left(3\right)+0.\left(384615\right)+\frac{3}{13}x}{0.0\left(3\right)+13}\)
Giups mik nha
tính A=\(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{85}+\frac{3}{50}+\frac{3}{65}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Bài 4: Tính
a) 0,(3) + \(\dfrac{10}{3}\) + 0,4(2) b) \(\dfrac{4}{9}\) + 1,2(31) - 0,(13)
c) 2,(4) x \(\dfrac{3}{11}\) d) -0,(3) + \(\dfrac{1}{3}\)
Tìm số tự nhiên x :
a) 2x + 3.(x+4) - 14 =8
b) x + 2.x + 3.x = 4.x + 16
c) 2.(x+1) + 3.(x + 5) = 0
d) ( x - 3 ).( x - 5 ) = 0
e) (2x - 40). (15 - 3.x) = 0
f) (3.x+6).(28-2.x) + 13 = 13
