hunter has a total of $9.60 in dimes and nickels. let n be the number of nickels and d be the number of dimes. hunter knows there are 12 more dimes than nickels. when the money values are in cents, the situation is modeled by this system of equations. 10d+5n=960 d=n+12 solve the system and determine what the solution means in terms of hunter's situation.

I love you and your family and friends is po box no yes no yes no yes

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
