Muriel translated the phrase below into an algebraic expression and then evaluated it for n = 4. the product of a number and 8

Which of the following contains the correct expression and value?

8 + n = 12
StartFraction 8 Over n EndFraction = 2
8 n = 32
8 minus n = 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

what is the original number? you forgot to add it.

13cm
