Let Cedric's age be c
tyshon= 3c-3
3c-3 +c =3c+c-3 = 4c-3
4c-3=57
4c=60
c=15
tyshon=15×3-3 = 42
        
             
        
        
        
m=18 when r = 2.
Step-by-step explanation:
Given,
m∝
So,
m = k× ,--------eq 1, here k is the constant.
,--------eq 1, here k is the constant.
To find the value of m when r = 2
At first we need to find the value of k
Solution
Now,
Putting the values of m=9 and r = 4 in eq 1 we get,
9 = 
or, k = 36
So, eq 1 can be written as m= 
Now, we put r =2 
m = 
or, m= 18
Hence,
m=18 when r = 2.
