Which inequality is graphed on the number line? please Hurry!!! OPTIONS:
A: 3a-11>7
B: 3a-11<7
C: 3a-11<=7
D: 3a-11>=7

Option C

Step-by-step explanation:

From the number line given in the picture,

Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.

Therefore, number line represents a ≤ 6

3a ≤ 3(6)

3a ≤ 18

3a - 11 ≤ 18 - 11

3a - 11 ≤ 7

Therefore, Option C is the correct option.

i leave the calculator work to you.

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
