Answer: 210 beats
Step-by-step explanation:
Given: A song has 28 beats in 4 seconds.
To find the rate of beats in song we need to divide 28 by 4, we get
⇒ Beats in each second of song=
To find the number of beats in 30 seconds, we need to multiply 30 to the rate of beats, we get
⇒Beats in 30 seconds of song=
Hence, there are 210 beats in 30 seconds of song.

Answer:
<u>Ravi</u> and <u>Courtney</u>
Step-by-step explanation:
<u>Simplifying the equations</u>
<u>Penny</u>
<u>Ravi</u>
- 2x + 3y = 3
- 3y = -2x + 3
- y = -2/3x + 3
<u>Courtney</u>
- -4x - 6y = -6
- 6y = -4x + 6
- y = -2/3x + 3
<u>Edwin</u>
- 6x + 6y = 9
- 6y = -6x + 9
- y = -x + 9
<u>Ravi</u> and <u>Courtney</u> would have infinitely many solutions because they are the same equation.
