What value of x is in the solution set of -2(3x+2)> -8x+6? a) -6 b)-5c) 5d) 6

-2(3x + 2) > -8x + 6

-6x - 4 > -8x + 6

2x - 4 > 6

2x > 10

x > 5

The solution set is all numbers greater than 5.

The only number greater than 5 in the choices is 6.

d) 6

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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
