Question

va rog cum se rezolva cu segmente a+b+c=72 a=b+12 c=b×4

Answer 1

a |------|-12-| } 72
b |------|
c |------|------|------|------|


72 - 12 = 60 ( 6 segmente egale )

60 : 6 = 10 ( un segment )

a = 10 + 12

a = 22

b = 10

c = 10 × 4

c = 40

Answer 2

a + b + c = 72
a = b + 12
c = b × 4
---------------
a , b , c = ?

b |----|
c |----|----|----|----| } 72
a |----|+ 12
72 - 12 = 60
60 : 6 = 10 b
10 × 4 = 40 c
10 + 12 = 22 a
