Answer 1

Răspuns:

R

Explicație pas cu pas:

a+23.076=31.000

a=31000-23076

a=7924

800.000-b=200.104

b=800000-200104

b=599896

c-42.309=15.008

c=15008+42309

c=57317

[(x-1):100+90]:10-10=0

[(x-1):100+90]:10=10

(x-1):100+90=100

(x-1):100=10

x-1=1000

x=999

d×9=21.339

d=2371

e:4=7.540

e=30160

126:f=63

f=126:63=2

g:4=307(rest 3)

g=307×4+3=1231

h:5=226(rest 2)

h=226×5+2=1132

901:i=100(rest 1)

i=(901-1):100=900:100=9
