Multiply the 2 by 3 to get 6 square yards
Then multiply that by three to get 18 square feet
Finally times 18 by 1.5 to get 12 tiles
Therefore 12 tiles are needed to cover the floor.
Answer: 6
Step-by-step explanation:
(24 - x)/2 = 9
multiply both sides by 2
24 - x = 18
subtract both sides by 24
-x = -6
multiply both sides by negative 1
x = 6
