Question

in 4 seringi pot fi 14 ml de ser fiziollogic reprezentand numere consecutive

Answer 1

Notam cu a,b,c,d cele 4 numere consecutive.
b=a+1
c=b+1=a+1+1=a+2
d=c+1=a+2+1=a+3
⇒a+b+c+d=a+a+1+a+2+a+3=14
⇒4a+6=14
4a=14-6
4a=8
a=8:4=2 ml
b=2+1=3 ml
c=3+1=4 ml
d=4+1=5 ml
VERIFICARE:
2+3+4+5=14
14=14

Answer 2

a+a+1+a+2+a+3=14
4a+6=14
4a=8
a=2
a+1=3
a+2=4
a+3=5
