p(x)= r(x)- c(x)
7x-20?
Answer:
Team A: 25 players
Team B: 24 players
Step-by-step explanation:
Team A:
to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:
![\frac{5}{x} = \frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bx%7D%20%3D%20%5Cfrac%7B1%7D%7B5%7D)
then we cross multiply to get
x*1 = 5*5
x=25 players
Team B
similarly to Team A
![\frac{3}{x} = \frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D%20%3D%20%5Cfrac%7B1%7D%7B8%7D)
cross multiply to get
x*1=3*8
x= 24 players
Answer:
Step-by-step explanation:
Cost of two tickets = 2 * 30 = £60
Let the amount with Puvi = £x
Money spent on dinner = (1/3)*x
![= \dfrac{1}{3}x](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B1%7D%7B3%7Dx)
![Remaining \ money =x - \dfrac{1}{3}x =\dfrac{3}{3}x-\dfrac{1}{3}x=\dfrac{2}{3}x](https://tex.z-dn.net/?f=Remaining%20%5C%20money%20%3Dx%20-%20%20%5Cdfrac%7B1%7D%7B3%7Dx%20%3D%5Cdfrac%7B3%7D%7B3%7Dx-%5Cdfrac%7B1%7D%7B3%7Dx%3D%5Cdfrac%7B2%7D%7B3%7Dx)
![Money \ spent \ on \ dessert = \dfrac{1}{4} *\dfrac{2}{3}x =\dfrac{1}{6}x\\\\\\](https://tex.z-dn.net/?f=Money%20%5C%20spent%20%5C%20on%20%5C%20dessert%20%3D%20%5Cdfrac%7B1%7D%7B4%7D%20%2A%5Cdfrac%7B2%7D%7B3%7Dx%20%3D%5Cdfrac%7B1%7D%7B6%7Dx%5C%5C%5C%5C%5C%5C)
Total money - money spent on dinner - money spent on dessert = 60
![x -\dfrac{1}{3}x -\dfrac{1}{6}x=60\\\\\\\dfrac{6}{6}x-\dfrac{1*2}{3*2}-\dfrac{1}{6}x =60\\\\\\\dfrac{6}{6}x-\dfrac{2}{6}x-\dfrac{1}{6}x=60\\\\\\\dfrac{6-2-1}{12}x=60\\\\\\\dfrac{3}{12}x=60\\\\\\x=60*\dfrac{12}{3}=60*4=240](https://tex.z-dn.net/?f=x%20-%5Cdfrac%7B1%7D%7B3%7Dx%20-%5Cdfrac%7B1%7D%7B6%7Dx%3D60%5C%5C%5C%5C%5C%5C%5Cdfrac%7B6%7D%7B6%7Dx-%5Cdfrac%7B1%2A2%7D%7B3%2A2%7D-%5Cdfrac%7B1%7D%7B6%7Dx%20%3D60%5C%5C%5C%5C%5C%5C%5Cdfrac%7B6%7D%7B6%7Dx-%5Cdfrac%7B2%7D%7B6%7Dx-%5Cdfrac%7B1%7D%7B6%7Dx%3D60%5C%5C%5C%5C%5C%5C%5Cdfrac%7B6-2-1%7D%7B12%7Dx%3D60%5C%5C%5C%5C%5C%5C%5Cdfrac%7B3%7D%7B12%7Dx%3D60%5C%5C%5C%5C%5C%5Cx%3D60%2A%5Cdfrac%7B12%7D%7B3%7D%3D60%2A4%3D240)
