Represent the proportional relationship described with an equation where p equals pillows and b equals beds:
2 answers:
Answer: A) p = 4b
Step-by-step explanation:
We know that the equation for direct variation between two quantities x( independent variable ) and y( dependent variable ) is given by :
, where k is proportionality constant.
Let p = Number of pillows and b= Number of beds.
If four pillows require for each bed, then
Number of pillows = 4 x (Number of beds)
i.e. p = 4 x (b)
i.e. p =4b
Hence, the equation that represents the proportional relationship described with an equation where p equals pillows and b equals beds:
p = 4b
Therefore , the correct answer is A) p = 4b.
