Answer:
Janine=12.6(repeating) Samantha=15.6(repeating) Lucy=19.6(repeating)
Step-by-step explanation:
Lets concentrate on one person, Janine.
<em>Janine = Lucy - 7</em>
<em>Janine = Samantha - 3</em>
If the averae of the 3 people's ages is 16, then we should multiple that by three to get 48, the number of their ages combined.
<em>Janine + Lucy + Samantha = 48</em>
The differences between Janine to Lucy and Janine to Samantha combined is 10, so we can subtract that from 48 to get 38, which is 3 times Janines age.
<em>38/3=12.6(repeating)</em>
That is Janine's age. We can use that to find both Lucy's and Samantha's ages respectively by using their equations. Lucy's is 19.6(repeating) and Samantha's is 15.6(repeating). I hope you can give me brainliest, and that this helped!
