A worker is installing blue and white square tiles in a kitchen. Blue tiles have different lengths than white tiles. A row of 8 blue tiles and 16 white tiles has a length of 39 inches. A row of 40 blue tiles and 8 white tiles has a length of 42 inches. Write a system of equations that represents in inches the relationship between the length of a blue tile and

8x + 16y = 39 and

40x + 8y = 42

Step-by-step explanation:

Let the length of the blue tiles is b inches and that of the white tiles is w inches.

So, given that a row of 8 blue tiles and 16 white tiles has a length of 39 inches and a row of 40 blue tiles and 8 white tiles has a length of 42 inches.

Therefore, we can write the system of linear equations that represents the relationship between the length if a blue tile and a white tile in inches as

8x + 16y = 39 and

40x + 8y = 42 (Answer)
