Answer 1

Răspuns:

1:

a)-8-4×2

-8-8=-16

b)11-42:3

11-14=-3

c)-284:(-4)+(-60)

71-60=11

d)-1600:(-8):25:(-4)

200:25:(-4)

8:(-4)

-2

e) -8+7-9-23

-1-32

-33

2:

x=-320

a) -320+24 =-296

b) -320:4= -80

3. x/9=5/3 => x=(9×5):3

x= 45:3

x = 15

4. 20/100 × x = -16

simplificam dractia 20/100 = 2/10

2/10×x=-16

2x/10=-16

2x=10×(-16)

2x= -160

x=-80

5. |x+36|=18

x+36= -18, +18

1. x+36= -18

x=-18-36

x=-54

2. x+36=18

x=18-36

x= -18
