What is the solution of the system of equations? 7x+2y=20

y=−7/2x+11

I need two solutions one for each

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

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man
