Answer:

Step-by-step explanation:

3 pieces such that each piece is 2 cm longer then the next...

x , x + 2, x + 4

x + x + 2 + x + 4 = 30

3x + 6 = 30

3x = 30 - 6

3x = 24

x = 24/3

x = 8

x + 2 = 8 + 2 = 10

x + 4 = 8 + 4 = 12

check...

8 + 10 + 12 = 30

18 + 12 = 30

30 = 30 (correct)...it checks out

the ribbon lengths are : 8 cm, 10 cm, and 12 cm

Answer:

They are 8, 10 and 12 cm long.

Step-by-step explanation:

Let the length of the shortest piece be x cm. Then:

x + x + 2 + x + 4 = 30

3x + 6 = 30

3x = 24

x = 8.
