Answer:
Your friend is wrong.
Step-by-step explanation:
Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:
C = kP.
Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.
C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.
Answer:
![\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
We need to find a rational number between 3/5 and 4/5.
We can find a rational number between two fractions as :
![\dfrac{a+b}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%2Bb%7D%7B2%7D)
We have, a = 3/5 and b = 4/5
So,
![\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B3%7D%7B5%7D%2B%5Cdfrac%7B4%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7B7%7D%7B5%7D%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7B10%7D)
So, a rational number between 3/5 and 4/5 is equal to 7/10.
