Ex. 3:
If y varies directly as x and y = 7 when x = 28,
find the constant of variation and write an
equation of direct variation.
Ex. 4:
If y varies directly as x and y = 6 when x = 10, find
the constant of variation and write an equation of
direct variation.
Ex. 5:
If y varies directly as x and y = 30 when x = 15,
find x when y = 50.
Ex. 6:
If y varies directly as x and y = 27 when x = 6, find
x when y = 45.
