Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k = 
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x
4.5 x 6.2 = 27.9

84 is 60% of 140!
To get this answer, you have to do 84 x 100 and you get 8400: Then you divide 8400 by 60 and get 140.
