Answer:
Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r =
no it's 4540
you just subtract 5220 from 9760 and you get your difference
80
70 + 30 = 100
180 - 100 = 80
55.76
