\(\frac{x}{-2,14}\)  = \(\frac{-3,12}{1,2}\) 

 \(\Rightarrow\)  \(x=\) \(\frac{\left(-3,12\right).\left(-2,14\right)}{1,2}\)  = \(5,564\)

\(x:\left(-2,14\right)=-3,12:1,2\)

\(x:\left(-2,14\right)=-2,6\)

\(x=-2,6\cdot\left(-2,14\right)\)

\(x=5,564\)

x : (-2,14) = (-3,12) : 1,2

x : (-2,14) = -2,6

x             = -2,6 x (-2,14)

x             = 5,564

Vậy x = 5,564

k cho mk nha !!!!

x:(-2,14) =(-3,12):1,2

x:(-2,14)=-2,6

x= -2,6.(-2,14)

x=5,564

\(x=-\frac{3,12}{1,2}\cdot\left(-2,14\right)\)

\(x=\) \(\frac{\left(-2,14\right).\left(-3,12\right)}{1,2}\) \(=5,564\)

x : (-2,14) = (-3,12) : 1,2

Suy ra: 1,2.x = (-2,14).(-3,12)

1,2.x = 6,6768

x = 6,6768: 1,2

x = 5,564.

=> x . (-2,14) = -2,6

=> x = 2,6/2,14

Cứ linh tinh đấy thì sao

X x 4 +119=235

hjhrhre

a) x : (-2,14) = (-3,12) : 1,2

=> x:(-2,14)= -2,6

=> x= -5,564

b) \(2\frac{2}{3}:x=2\frac{1}{12}:\left(-0,060\right)\)

=> \(\frac{8}{3}:x=\frac{-625}{18}\)

=> x= \(\frac{8}{3}:\frac{-625}{18}\)

=> x= \(\frac{-48}{625}\)

a) x : ( -2,14) = (-3,12) :1,2

x : ( -2,14) = -2,6

x = -2,6 x ( -2,14)

x = 5,564

Vậy x = 5,564

b)\(2\dfrac{2}{3}\) : x = \(2\dfrac{1}{12}\) : ( -0,06)

\(2\dfrac{2}{3}\) : x = \(-\dfrac{625}{18}\)

x = \(2\dfrac{2}{3}\) : \(-\dfrac{625}{18}\)

x =

a)x : (-2,14) = (-3,12) : 1,2

x : (-2,14) = -2,6

x = (-2,6) * (-2,14)

x = 5,564

b)8/3 : x = 25/12 : (-0,06)

8/3 : x = -625/18

x = 8/3 : -625/18

x = -48/625 = -0,0768

Đó là đáp án của em ạ , mong thầy duyệt.
