Răspuns:
a=16
b=24
c=32
Explicație pas cu pas:
[tex]\frac{a+b+c}{3} =24[/tex]
a+b+c=72
b = a+a/2 = 3a/2
c= b+b/3 =4b/3
a+3a/2+6a/3=72
(6a+9a+12a)/6=72
27a=432
a=16
b=24
c=32
Răspuns:
[tex]\frac{a+b+c}{3} =24\\\\a+b+c=24*3=72\\\\b = 150a/100 = 15a/10 = 3a/2\\\\c = b + b/3 = > c= 4b/3\\\\a = 2b/3\\\\2b/3 + b + 4b/3 = 72 \\\\numitor.comun-3\\ \\2b + 3b + 4b = 216= > 9b = 216= > b = 216 : 9= > b = 24\\ \\a = 2*24:3 = 16\\\\c = 4*24:3= 32\\\\[/tex]
