2 because you make them with the same denominators that both go into each other EX: 8x9=72 7/8 now equals 63/72 and 4/9 now equals 28/72 now add them together 63/72 + 28/72= 91/72= 1 19/72
Step-by-step explanation:
answer A is correct
................
Answer:
y is less than or equal to 1 OR y is greater than or equal to 6
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
There are 12 inches in a foot.
Therefore in 8 feet there are 96 inches
Therefore the square floor is 96 * 96.
Therefore the area of the square floor is 9216 inches squared.
Each tile is 8 inches by 8 inches meaning it has an area of 64 inches squared.
9216 / 64 = 144.
Therefore 144 tiles are needed to tile the floor
Since each tile is 50 cents, 144 * 0.5 = 72
Therefore it costs 72 dollars to tile the floor.
