Keisha, Felipe, and Manuel sent a total of 100 text messages during the weekend. Keisha sent 8 more messages than Felipe. Manuel

Karo-lina-s [1.5K]

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.

Step-by-step explanation:

Given that 6 freshmen, 5 sophomores, 6 juniors, and 5 seniors are eligible to be on a committee

16 students be chosen if it is to consist of exactly 4 juniors and exactly 3 seniors, and the rest must be freshmen or sophomores

i.e. dance committee will have 16 students out of which

4 juniors 3 seniors 8 freshmen or sophomores from

6 juniors, 5 seniors and 5 sophomores and 6 freshmen

Junior can be selected in 6C4 = 15 ways

Seniors in 5C3 = 10 ways

Freshman or sophomores in 11C8 = 165

The total no of ways = product of these three

= $15*10*165\\= 24750$
