The table represents a proportional relationship.
x= 3, 6, 12, 24
y= 1, 2, 4, 8
which equation matches the values in the table

A. y= 2r
B. y= 1/2x
C. y= 3x
D. y= 1/3x

Step-by-step explanation:

Take the first value of y i.e = 1

if 3 is multiplied with the value of y we get the first value of x

y=1

x=3(1)

=3y

Similarly, again when y=2

x=3×2=6

Again taking y=4

x=3×4=12

Therefore, we conclude that,

x=3y

or,y=1/3x

option D

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
