Question

in trei hambare sunt 153 t cereale.daca in primele doua sunt 89 t iar in ultimele doua 97 t cate quintale de cereale sunt in fiecare hambar.

Answer 1

a+b+c=153t
a+b=89t
b+c=97t
89+c=153
c=153-89
c=64t
a+97=153
a=153-97
a=56t
a+b=89
b=89-56
b=33t=33000kg=330q
a=56t=56000kg=560q
c=64t=64000kg=640q
formula de transformare folosita este:
1t=1000kg=10q
