Answer:
He used 17/3 feet = 5 and 2/3 feet
Step-by-step explanation:
∵ He bought 9 and 1/3 feet = 28/3 feet
∵ He had 3 and 2/3 feet left = 11/3 feet
∴ He used = 28/3 - 11/3 = 17/3 feet = 5 and 2/3 feet
x=1/6 or 1.16 (6 repeating) or x=6^-1
y=6x-1
substitute y =0
0=6x-1
Move the variable to the left
-6x =-1
Divide on both dies
4 : 8
x 9 => 36 : 72 <=== equivalent
