ella [17]

Answer:

Step-by-step explanation:

Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.

No

because

       2 ≠ 5

If they each used the same number of tiles, how many tiles were in each box?

6x + 2 = 5x + 17

6x - 5x + 2 - 2 = 5x - 5x + 17 - 2

        x = 15 tiles
