Пошаговое объяснение:

-95:5+89=-19+89=70

-46+48:6=-46+8=-38

27/28*14/36-1/8 =3/8-1/8=2/8=1/4

(4/5-7/20)*45/36 =9/20×45/36=9/16

-8.3-1.6*7.5=-8.3-12=-20.3

(-9.3+1.8):1.5 =-7.5:1.5=5

(6х+2)-4х; х=-6

6x+2-4x=2x+2=2×(-6)+2=-12+2=-10

8х-4*(х-3)+15; х=6

8x-4x+12+15=4x+27=4×6+27=24+27=51

1)-95/5+89=70

2) -46+48:6= -46+8=38

3) 27/28*14/36-1/8=378/1008-(1/8)^126=378/1008-126/1008=252/1008=1/4

4) (4/5-7/20)*45/36=(16/20-7/20)*45/36=9/20*45/36=405/720=9/16

5)-8,3-1,6*7,5=-8,3-12=-20,3

6) (-9,3+1,8)/1,5=-7,5/1,5=-5

7) (6х+2)-4х; х=6

(-36+2)-24=-34-24=-10
