Question

Aflati doua nr, stiind ca media lor aritmetica este 6,06 si catul nr este 14,15.

Answer 1

(a+b):2= 6,06
a:b=14,15 => a= 14,15 b
14,15b+b = 12,12
15,15b=12,12
b=0.8 => a=12,12 - 0,8, a= 11,32

Answer 2

Ma=$\frac{a+b}{2}$
6,06=$\frac{a+b}{2}$
a+b=2x6,06------> a+b=12,12------>a=12,12-b
a:b=14,15
12,12-b:b=14,15-----> 12,12=15,15b ----->b=$\frac{12,12}{15,15}$=0.8
a+b=12,12----> a=11,32
