Melanie runs around the track at a rate of 1 mile every 8 minutes. If her running rate remains the same, which method could be u sed to determine the number of minutes for her to run 5 miles?
1 answer:
Option number 3. this is the answer because she runs a mile in 8 minutes, so in order to find out how much it would take to run 5 miles, you would multiply 5 by 8.

4(3x 5) multiply everything by 4
12x+20
1. x = 1 2. x = -30 3. x = -2 4. x = 15 5. x = 7, y = 11 6. x = 4, y = 1
7. x = 1/2, y = 25/5 8. x = 1/4, y = 11/2

Step-by-step explanation:
7. Since they are similar triangles we have:
So DF is 15
8 . They are also similar. So:
So PR is 10
3(100-b) = 6b
