Answer:
Felipe = 23 messages
Keisha = 31 messages
Manuel = 46 messages
Step-by-step explanation:
Keisha = K
Felipe = F
Manuel = M
=> There are a total of 100 messages.
=> K sent 8 +F => K = 8 + F
=> M sent 2 * F => M = 2F
=> F = F
=> 8 + F + 2F + F = 100
=> 8 + 4F = 100
=> 8 - 8 +4F = 100 -8
=> 4F = 92
=> 4F/4 = 92/4
=> F = 23
So, Felipe = 23 messages.
Keisha = 8 + F = 8 + 23 = 31 messages.
Manuel = 2F = 2* 23 = 46 messages.
46 + 31 + 23 = 77 + 23 = 100 messages.
So, the answer is correct.

Answer:
n = 8.
Step-by-step explanation:
The 2 lines are the same length so
4n + 12 = 2n + 28
4n - 2n = 18 - 12
2n = 16
n = 8.
If you're looking for the interest the answer would be:
i=8,000*.015*3
i=360.
The interest would be $360 dollars.
The balance would be 8,000+360= $8,360
