Answer:
4 tiles
Step-by-step explanation:
Area of a square tile:
A = s²
A = (30)²
A = 900 cm
900 cm = 9 m
Area of the square room:
A = s²
A = (6)²
A = 36 m
36 ÷ 9 = 4
Answer:10-w<u>< </u> 8
Step-by-step explanation:
5(n-4)=(4n-12)
First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.
Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.
(5n-20)=(4n-12)
n-20=-12
Next: Add 20 to both sides to eliminate the constant from the left side of the equation.
n-20=-12
n=8
The unknown number is 8.
