Step-by-step explanation:
Answer: The constant proportionality is 5/4
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
X=Marks sister's age
x+11= Marks age
x+11 +8 = 2x+8
x+19=2x +8
x+19-x=2x-x +8
19-8=x+8-8
11=x Marks sisters age in 8 years
11-8= 3 Marks sisters age now
x+11=22 Marks age in 8 years
22-8= 14 Marks age now
The factors of a number are all of the numbers that a certain number is divisible by. In this case, we're looking for all the numbers that 
is divisible by.
To do this, I'll use factor pairs. This means I will find the pairs of numbers that can be multiplied together to get 42.
So, all of the factors of 42 are 
.
