\(\dfrac{-11}{31}\cdot\dfrac{-2}{17}+\dfrac{7}{31}\cdot\dfrac{-20}{17}-\dfrac{9}{17}\cdot\dfrac{11}{31}\)
Tìm x:
a) \(-\dfrac{3}{5}\) - x = -0,75
b) \(1\dfrac{4}{5}\) = -0,15 - x
c) x + \(\dfrac{1}{3}\) = \(\dfrac{2}{5}\) - ( \(-\dfrac{1}{3}\) )
\(\left(-0,75.x+\dfrac{5}{2}\right).\dfrac{4}{7}-\left(-\dfrac{1}{3}\right)=\dfrac{-5}{6}\)

HELP ME!
\(A=\left(\dfrac{-40}{51}.0.32.\dfrac{17}{20}\right):\dfrac{64}{75}\)
\(\dfrac{-10}{13}\)+\(\dfrac{5}{7}\)-\(\dfrac{3}{13}\)+\(\dfrac{2}{17}\)-\(\dfrac{11}{20}\)
( làm chi tiết )
\(-2\frac{1}{5}\&\frac{110}{-50};\frac{17}{20}\&0,75\)
