let's say that number is "x", so that is then the 100%.
if 150 is 25%, what is "x"?
Answer:
2y = x, which is a proportional relationship.
Step-by-step explanation:
See the table attached.
The table gives the ordered pair represents a proportional relationship.
Take at least two pairs of the value of x and y.
Let they are (6,3) and (10,5).
Now, the equation for the straight line passing through the two points is given by
⇒ 2(y - 5) = x - 10
⇒ 2y - 10 = x - 10
⇒ 2y = x
Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
