Ответ:
1) 0.85
2) -38.75
3) -86
4) 12.25
Пошаговое объяснение:
1. -0.5×(-2.125)×(-0.8)+9.35=0.85
1) -0.5×(-2.125)=10.625
2) 10.625×(-0.8)= -8.5
3) -8.5+9.35=0.85
2. -5.4×3.125×(-0.4)-32= -38.75
1) -5.4×3.125=16.875
2) 16.875×(-0.4)= -6.75
3) -6.75-32= -38.75
3. 1.28×(-2.25)×3.5-45.92= -86
1) 1.28×(-2.25)= -2.88
2) -2.88×3.5= -40.08
3) -40.08-45.92= -86
4. -6.75×(-10)×(-1.3)+100=12.25
1) -6.75×(-10)=67.5
2) 67.5×(-1.3)= -87.75
3) -87.75+100=12.25
