Question

Afla trei numere,stiind ca doua cate doua au media aritmetica egala respectiv cu:39,46,50

Answer 1

(a+b):2=39
a+b=39*2
a+b=78

(a+b):2=46
a+b=46*2
a+b=92

(a+b):2=50
a+b=50*2
a+b=100

2a+2b+2c=78+92+100
2*(a+b+c)=170+100
2*(a+b+c)=270
a+b+c=270:2
a+b+c=135


a=135-78
a=57

b=135-100
b=35

c=135-92
c=43

Verificare

a+b+c=57+35+43=92+43=135
