7) the answer i think... is A. 500 yd
i figured this out by just measuring the line and since it's about 2 of the scale, 250 x 2 = 500.
8)The answer is A. 1 in = 6 ft
21 x 6 = 126 and 12 x 6 = 72 and since they were in inches, then when you multiply it has to be in feet.
can't do 9... because i have to get off... sorry, but hoped this helped you :)
