Answer:
5
Step-by-step explanation:
The constant of proportionality k is calculated as
k = [tex]\frac{gallons}{time}[/tex]
Then
k = [tex]\frac{5}{1}[/tex] = [tex]\frac{10}{2}[/tex] = [tex]\frac{15}{3}[/tex] = [tex]\frac{35}{7}[/tex] = [tex]\frac{50}{10}[/tex] = 5
the constant of proportionality in the table is 5.
the answer is 5 because 1 x 5 = 5 ,2 x 5=10 , 3 x 5 = 15 , 7 x 5 = 35, and 10 x 5 = 50.
