Question

Ex 6 vă rog tare mult!!!!!

Answer 1

Răspuns:

a + b + c = 120

a = 2k

b = 3k

c = 5k

2k + 3k + 5k = 120

10k = 120

k = 12

a = 24

b = 36

c = 60

a + b + c = 120

a = 3k

b = 5k

c = 7k

3k + 5k + 7k = 120

15k = 120

k = 8

a = 24

b = 40

c = 56

a + b + c = 120

a = 4k

b = 3k

c = 13k

4k + 3k + 13k = 120

20k = 120

k = 6

a = 24

b = 18

c = 78

a + b + c = 120

a = 5k

b = 7k

c = 12k

5k + 7k + 12k = 120

24k = 120

k = 5

a = 25

b = 35

c = 60
