x = 4, y = 7.5, z = 13.25
Explicație pas cu pas:
x + y + z=24.5
x/1.6 = y/3 = z/5.2 = k
k - coeficient de proportionalitate
x = 1.6k
y = 3k
z = 5.2k
1.6k + 3k + 5.2k = 24.5
9.8k = 24.5
k = 2.5
x = 1.6k =>x = 1.6 x 2.5 = 4
y = 3k =>y = 3 x 2.5 = 7.5
z = 5.2k =>z = 5.2 x 2.5 = 13.25
Verificare:
4 + 7.5 + 13.25 = 24.5
