Question

EXERCIȚIUL 5: AFLA A+B+C in fiecare caz

Answer 1

Răspuns:

Explicație pas cu pas:

a) a = 2 x b => a = 2 x c/3

c= 24

a = 2 x 24/3 = 2 x 8 = 16

b = 8

=> a + b + c = 48

b) c = 6

b = 24 / 6 = 4

a = 4 + 4 = 8

=> a + b + c = 18

c) c = 54

b = 54 / 9 = 6

a = 6 + 6 =12

a + b + c = 72
