Ответ:
[tex]\displaystyle -6,2*2\frac{3}{14}+2\frac{3}{14}*(-1,8)-8*(-1\frac{19}{56} ) = -7[/tex]
Пошаговое объяснение:
[tex]\displaystyle -6,2*2\frac{3}{14}+2\frac{3}{14}*(-1,8)-8*(-1\frac{19}{56} ) = 2\frac{3}{14}*(-6,2+(-1,8))+8*\frac{75}{56} = \\ = \frac{31}{14} *(-8)+8*\frac{75}{56} = 8*(-\frac{31}{14} +\frac{75}{56} ) = 8*\frac{-31*4+75}{56} = 8*\frac{-124+75}{56} = -49*\frac{8}{56} =-\frac{49}{7} = -7[/tex]
