Solve 4x- c= k for x. A. x = 4(k+ c)
B. x = k +c / 4
C. x = k-c/4
D. x = 4(k - c)

B. x = k +c / 4

Step-by-step explanation:

4x- c= k

4x=k+c

x=k+c/4

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

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
