Answer:
I believe that Kevin is 6 years old now.
Step-by-step explanation:
I used the guess and check method to figure this out.
First, I began by making Daniel 1 years old, two years ago. Kevin was 4 times as old as Daniel two years ago, so he would be 4 at the time. Now, Daniel would be 3 and Kevin would be 6 years old. The statement that Kevin is three years older than Daniel would confirm this, because 6-3=3. Hope this helps, this is my first time answering:)

Answer:
Richard gets 9
Andrew gets 21
Step-by-step explanation:
We know they got money in the ratio 3:7
So we multiply up until we reach 30 because we know 3 + 7 = 10
3:7 = 6:14 = 9:21
9:21 is equal to 30 so it is the answer
Break it down and you get those answers
