Question

Aflati doua numere stiind ca media lor aritmetica este 6,06 si catul numerelor este14,15.

Answer 1

              
$\frac{x+y}{2}=6,06 \\ \frac{x}{y}=14,15 \\ --- \\ x+y=2*6,06 \\ x=14,15y \\ --- \\ x+y=12,12 \\ x-14,15y=0 \\ \text{--------------------- din prima ecuatie o scadem pe a doua} \\ /\;\;\;\;\;15,15y =12,12 \\ \\ y = \frac{12,12}{15,15}= \frac{12*1,01}{15*1,01} = \frac{12}{15}= \frac{4}{5}=\boxed{0,8} \\ \\ x+0,8=12,12 \\ x=12,12-0,8= \boxed{11,32}$
