Question

Află numerele necunoscute.
c) (32 : w) - 6 = 12:6
b) (z: 8) + 18 = 7 x3
a) 36:9 x y = 28. Repede va rog​

Answer 1

Răspuns:

a) 4×y= 28

y= 28:4

y= 7

b) (z:8)+18=21

z:8= 21-18

z:8= 3

z=3×8

z=24

c) (32:w)-6= 2

32:w= 2+6

32:w= 8

w= 32:8

w= 4

Answer 2

Salutare!

(32:w)-6=12:6
(32:w)-6=2
32:w=2+6
32:w=8
w=32:8
w=4

(z:8)+18=7•3
(z:8)+18=21
z:821-18
z:8=3
z=3•8
z=24

36:9•y=28
4•y=28
y=28:4
y=7
