va rog mult de tot
1,2,3

Answer 1

1)
528-3=525
525:3=175(primul numar)
176(al doilea numar)
117(al treilea numar)

2)
a+b=80
a-b=>a=6+b
b+6+b=80
2b+6=80
2b=80-6
2b=74
b=74/2=>b=37=>a=6+37=43

3)

a,b,c,d-nr.cautam
a,b,c,d-nr.nat.impare consecutive
a+b+c+d=1656
b=a+2
c=a+4
d=a+6 
------------
a,b,c,d=?
------------------
a+a+2+a+4+a+6=1656
4a=1656-12
4a=1644
a=1644:4
a=411
b=411+2
b=413
c=411+4
c=415
d=411+6
d=417
Raspunsul cel mai mare numar este 417.
Sper ca te-am ajutat!
