Question

6:(-1.5)-4.6+5(2а-3) (-1.6с+0.4)-(0.5-0.8)с 1-(1.5х-2)-4(0.5х-1.1) - 1\4+(-3\4)-2\9+(-4\9) 6-(-0.2):0.4+0.8-2.4:6

Answer 1

6:(-1.5)-4.6+5(2а-3)=-4-4,6+10а-15=10а-23,6

(-1.6с+0.4)-(0.5-0.8)с=-1,6с+0,4-0,5с+0,8с=0,4-1,3с

1-(1.5х-2)-4(0.5х-1.1)=1-1,5х+2-2х+4,4=-3,5х+х7,4

- 1\4+(-3\4)-2\9+(-4\9)=(-1/4-3/4)-(2/9+4/9)=(-4/4)-(6/9)=-1-6/9=-1

 

6-(-0.2):0.4+0.8-2.4:6=6-(-0,2/0,4)+0,8-2,4/6=6+0,5+0,8-0,4=6,9

Answer 2

-4-4.6+10а-15=10а-23,6

-1,6с+0,4-0,5с+0,8с=0,4-1,3с

1-1,5х+2-2х+4,4=7,4-3,5х

-1/4-3/4-2/9-4/9=-1-6/9= - 1 2/3

-1,2:0,4+0,8-0,4=-3+0,8-0,4=-2,6
