A83 -centimeter-long board is cut into 3 pieces. the longest piece is twice as long as the shortest piece. the other piece is 7 cm longer that the shortest piece. how long is each piece?

longest piece is 38 cm

medium piece is 26 cm

smallest piece is 19 cm

Step-by-step explanation:

Let's assume longest piece is x cm

medium piece is y cm

smallest piece is z cm

The longest piece is twice as long as the shortest piece

so,

The other piece is 7 cm longer that the shortest piece

so,

A 83 -centimeter-long board is cut into 3 pieces

so,

now, we can plug these equations

now, we can solve for z

now, we can find x and y

so,

longest piece is 38 cm

medium piece is 26 cm

smallest piece is 19 cm
