tìm x ,biết
a, 0,5x-2/3x=7/12
b, x : 4\(\frac{1}{3}\) = -2,5
c, 5,5x =13/15
d ,{\(\frac{3x}{7}\)+1} : -4 = \(\frac{-1}{28}\)
Tim x biet :
a, 0,5x - \(\frac{2}{3}\)x = \(\frac{7}{12}\) b, \(\left(\frac{3x}{7}+1\right):\left(-4\right)=\frac{-1}{28}\)
a) 0,5x-\(\frac{2}{3}\)x = \(\frac{7}{12}\)
b) 5,5x = \(\frac{13}{15}\)
c) (\(\frac{3x}{7}\)+1) : (-4) =\(\frac{-1}{28}\)
giải chi tiết giúp mik nha. Thanksss
Tìm x, biết :
\(a.0,5x-\frac{2}{3}x=\frac{7}{12}\) \(b.x:4\frac{1}{3}=-2,5\)
\(c.5,5x=\frac{13}{15}\) \(d.\left(\frac{3x}{7}+1\right):\left(-4\right)=-\frac{1}{28}\)
a ) 0,5x - \(\frac{2}{3}\)x = \(\frac{7}{12}\)
b) x : 4\(\frac{1}{3}\)= -2,5
c) 5,5x = \(\frac{13}{15}\)
d) \(\left(\frac{3x}{7}\right)\)+1 : ( - 4 ) = \(\frac{-1}{28}\)
( Tìm x , cho mình cách giải với nhé ^^! )
Tìm x biết:
A) \(0,5x-\frac{2}{3}x=\frac{7}{12}\) B)\(x:4\frac{1}{3}=-2,5\)
C)\(5,5x=\frac{13}{15}\) D)\(\left[\frac{3x}{7}+1\right]:\left(-4\right)=\frac{-1}{28}\)
Tìm x
x + \(\frac{30}{100}\)x = -1,3
( \(\frac{3}{7}x+1\) ) : (-4) = \(\frac{-1}{28}\)
0,5x - \(\frac{2}{3}x\) = \(\frac{7}{12}\)
Bài 1: Tính:
\(\frac{1}{4}+\frac{7}{12}-\frac{6}{13}-\frac{7}{8}\)
Bài 2: Tìm x:
0,5x - \(\frac{2}{3}\)x = \(\frac{5}{12}\)
\(x-40\%\times x=3,6\)
\(3\frac{2}{7}\times x-\frac{1}{3}=-2\frac{3}{4}\)
\(-\frac{4}{7}+\frac{5}{7}\div x=\frac{1}{6}\)
\(\left(\frac{3x}{7}+1\right)\div\left(-4\right)=-\frac{1}{28}\)
\(-\frac{3}{x-2}=\frac{4}{-20}\)
