Tìm y: 0,3 x ( y + $\frac{1}{3}$ ) = $\frac{1}{2}$ x ( 0,81 : 2,7 ) 02/10/2021 Bởi Mackenzie Tìm y: 0,3 x ( y + $\frac{1}{3}$ ) = $\frac{1}{2}$ x ( 0,81 : 2,7 )
ta có: 0,3 . (y+1/3) = 1/2 . 0,3 => y+1/3 = 1/2 => y= 1/2 – 1/3 => y= 1/6 vậy y=1/6 Xin hay nhất nha Bình luận
0,3x (y+ 1/3) = 1/2 x 0,3 3/10 x(y+1/3)= 3/20 y+ 1/3 = 3/20 : 3/10 y+ 1/3= 1/2 y= 1/2 -1/3 y= 1/6 Vậy y= 1/6 Bình luận
ta có:
0,3 . (y+1/3) = 1/2 . 0,3
=> y+1/3 = 1/2
=> y= 1/2 – 1/3
=> y= 1/6
vậy y=1/6
Xin hay nhất nha
0,3x (y+ 1/3) = 1/2 x 0,3
3/10 x(y+1/3)= 3/20
y+ 1/3 = 3/20 : 3/10
y+ 1/3= 1/2
y= 1/2 -1/3
y= 1/6
Vậy y= 1/6
