A 9-foot board is cut into two pieces. If one piece is X feet long, express the other length in terms of x

Respuesta :

if the two pieces are X and Y, and one is X feet then to find the other just subtract X from the total. it would be Y = 9 - X

Answer:

9 - X

Step-by-step explanation:

Total length of a board = 9 foot

Let there are two pieces of the board.

length of one piece of the board = X

Length of other piece of the board = Y

According to the question,

sum of the length of two pieces = 9 foot

X + Y = 9

Y = 9 - X

Thus, the length of other piece is 9 - X.
