Verified answer

Ответ:

1) -16.78

2) 5.1243

3) -[tex]\frac{85}{36} = -2\frac{13}{36}[/tex]

4) -[tex]\frac{11}{3} = -3\frac{2}{3}[/tex]

Объяснение:

1) -8.04-8.74=-16.78

2) -16.53(-0.31)=5.1243

3) [tex]\frac{8}{9} *(-\frac{53}{16})-\frac{29}{6} *(-\frac{7}{58} )[/tex] =

= [tex]-\frac{8}{9} *\frac{53}{16}+\frac{29}{6} *\frac{7}{58} = -\frac{1}{9} *\frac{53}{2}+\frac{1}{6}*\frac{7}{2}=-\frac{53}{18}+\frac{7}{12}=-\frac{85}{36}=-2\frac{13}{36}[/tex]
