ii) how old is kenneth?

Answer 1

Answer:

Kenneth-12years Randy-48years

Step-by-step explanation:

Let Kenneth be x years old and Randy be y years old.

Then, y=4x -(i) and y=x+36 -(ii)

put y=4x in eq(ii),

4x=x+36 -> 4x-x=36 -> 3x=36 -> x=12

Now, y=4x=4*12=48

So, Kenneth is 12 years old and Randy is 48 years old.

I) 48

ii)12
