Answer:
k=20
Step-by-step explanation:
The constant of proportionality, k, measures the constant value of the ratio between two proportional quantities, being y and x in this case. Essentially, y/x will always equal 20, the constant of proportionality.
The mean is 42.6
the answer could be 10/3 and decimal form is 3.3 and mixed form is 3 1/3 (i hope this helps sorry if I'm wrong!)
