:)

Answer 10

nott 20 nono

Answer 11

its 1/20 so 0.05

Answer 12

x = 20,000
y = 1,000

y/x = 1,000/20,000 = 0.05

y = 0.05 x

The constant of proportionality is 0.05 (5 percent).

Look at the other points just to check it out and see if it holds water:

x = 1,500
y = 30,000
x/y = 0.05 yes !

x = 2,000
y = 40,000
x/y = 0.05 yes !
