Urgent!!!! ​

Answer 1

Răspuns:

Explicație pas cu pas:

15/90*a = 125/1000*b=75/900*c

a/6=b/8=c/12

a/6=b/8 ⇒ b=8a/6

a/6=c/12 ⇒ c=12a/6 c=2a

2ab +5bc - 6ac = 1/12*abc

2a*8/6*a + 5 *8/6*a *2a -6a*2a = 1/2 *a *8/6*a *20

16a² /6 +80a²/6 -12a² = 8a³/6

16a² +80a² -72a² = 8a³

24a² =8a³  : 8²

a=3

b= 8*3/6  b=4

c= 2*3     c= 6
