Question

1) stiind ca
a+b+c=32
a=15-b
calculeaza-l ce c



2) stiind ca

a+b=100
b+c=110
a+c=90
calculeaza
a=
b=
c=


3) a+b=967
b+c=1326
a+b+c=1520
da coroana la cine raspunde corect si intreb

Answer 1

1.
a= 15-b deci 15-b+b+c=32=>15+c=32=>c=32-15=17
2.
2a+2b+2c=100+110+90=300=> a+b+c=200:2=150
daca a+b=100=>c=50
daca b+c=110 si c=50=>b=60
a=150-50-60=40
a=40,b=60,c=50
3.
banuiesc ca trebuie sa aflii a b si c.
a+b+c=1520
a+b=967
1520-967=553=c
b+c=1326
1520-1326=194=a
b=1520-553-194=773
a=194,b=773,c=553
