Question

Rezolvareeeeee!!!!!!!​

Answer 1

Răspuns:

x = 16

y = 24

z = 36

Explicație pas cu pas:

$\frac{x}{2} = \frac{y}{3} = \frac{z}{7}$ = k

$\frac{x}{2} = k -> x = 2k$

$\frac{y}{3} = k -> y = 3k$

$\frac{z}{7} = k -> z = 7k$

Mergem cu toate necunoscutele in relatia a doua:

x * y * z = 336

2k * 3k * 7k = 336

42 * k = 336

k = 336 : 42

k = 8

x = 2k = 2 * 8

x = 16

y = 3k = 3 * 8

y = 24

z = 7k = 7 * 8

z = 56
