Answer:
Step-by-step explanation:
The measure of the floor of the rectangular room that is 12 feet by 15 feet. The formula for determining the area of a rectangle is expressed as
Area = length × width
Area of the rectangular room would be
12 × 15 = 180 feet²
The tiles are square with side lengths 1 1/3 feet. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet
Area if each tile is
4/3 × 4/3 = 16/9 ft²
The number of tiles needed to cover the entire floor is
180/(16/9) = 180 × 9/16
= 101.25
102 tiles would be needed because the tiles must be whole numbers.

Answer:
y=-2/7x+60/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(8-10)/(2-(-5))
m=-2/(2+5)
m=-2/7
y-y1=m(x-x1)
y-10=-2/7(x-(-5))
y-10=-2/7(x+5)
y=-2/7x-10/7+10
y=-2/7x-10/7+70/7
y=-2/7x+60/7
x = -14
-6(-14) + 6y = 42
84 + 6y = 42
subtract 84 from both sides: 6y = -42
divide by 6: y = -7
when x = -14, y = -7
