Answer:
x=5
Step-by-step explanation:
let x be the number
1+6x = 6+5x
6x-5x=6-1
x=5

Lol seems like elementary but 17.50 minus 9.50 equals 8 so the basic change is 8. X'D I cant believe this is college X'D
First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)
27pi=84.823
rounded, 84.82
