Question

un cal , un hipopotam si balena au impreuna masa de 1257q. un cal si un hipopotam au impreuna 27q, iar un hipopotam si o balena au 125t.
calculeaza in kg masa fiecarui animal.

Answer 1

h+b=125 t=1250 q
27+b=1257 q
b=1257-27    b=1230 q=12300 kg
h+1230=1250
h=1250-1230     h=20 q=200 kg
c+20=27 
c=27-20     c=7 q=70 kg
R: c=70 kg; h=200 kg; b=12300 kg

Answer 2

C=cal
H=hipopotam
B=balena
C+h+b=1257q
C+h=27q
H+b=125t=1250q
1257-27=1230q(balena)
1257-1250=7(calul)q
27-7=20(hipopotamul)
