Mathematics
1 answer:
9966 [12]4 years ago
5 0

Answer:

Kenny is 18 years old Andrew is 10 years old Tim is 30 years old and Cameron is  5 years old

Step-by-step explanation:

Let a be Kenny's age , b be Andrew's age , c be Tim's age , d be Cameron's age

( b < a , b<c , d<b)

Kenny is 8 years older than Andrewn = > a = b + 8 (1)

Tim is 3 times  as old as Andrew => c = 3 . b (2)

Cameron is 5 years younger than  Andrew => d = b-5 (3)

The combined age of the four is 63 => a+b+c+d = 63 (4)

(1),(2),(3),(4) => b+8 + b + 3b + b-5 = 63 <=> 6b + 3 = 63 <=> b = 10

=> a= 10+8 =18, c = 3 . 10 = 30, d= 5
