Question

If y is directly proportional to x and y=100 when x=10, find
an equation connecting x and y
the value of y when x=5,
the value of x when y=80.

Answer 1

Answer:

y is directly proportional and when y=100, x=10(that is, x=1/10 th of y)

so, when x=5 , y=10×x=10×5=50

when y=80, x=1/10 ×80 =8
