6(w-1)=3(3w+5)(if there is no solution, type in ''no solution)w= answer

the answer is "w = -7"

Step-by-step explanation:

6*(w-1) = 3*(3*w + 5)

--> 6*w - 6 = 9*w + 15

--> 9 * w - 6 * w = -6 -15

--> 3 * w = -21

--> w = -21 / 3

--> w = -7

3

Step-by-step explanation:

multiply the no. in the brackets

6w-6=9w+15

collect like terms

9w-6w=15-6

3w=9

divide both sides by 3w

3w/3 = 9/3

w=3

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
