Va rog am nevoie de el rezolvat urgent. Dau coroana​

Answer 1

a = primul număr

b = al doilea număr

Media aritmetică = ( a + b ) : 2 = 14, 35

a : b = 7, 2

a + b = 14, 35 × 2

a + b = 28, 7

a = 7, 2 × b

7, 2 × b + b = 28, 7

8, 2 × b = 28, 7

b = 28, 7 : 8, 2

b = 287 : 82

b = 3, 5

a = 7, 2 × 3, 5

a = 25, 2
