Question

află valoarea termenului necunoscut (dau coroana)​

Answer 1

Răspuns:

1×2×3×a=24

6×a=24

a=24:6

a=4

b×2×5=40

b×10=40

b=40:10

b=4

c:2:3=5

c=5×3×2

c=30

27:3:3×d=6×4

3×d=24

d=24:3

d=8

e:8+2000=2003

e=(2003-2000)×8

e=3×8

e=24

(6×6-27)×f=81

9×f=81

f=81:9

f=9

(394-123-g):2=108

271-g=108×2

-g=54-271

-g= -217

g=217

6×5:10+h=296

3+h=296

h=296-3

h=293

[(124+692)-400×2]:i=4

(816-800):i=4

16:i=4

i=16:4

i=4

(24:3+45:5)+143=4×j+124

17+143=4j+124

-4j= 124-160

j= -36:(-4)

j= 9
