Question 941607: A company mixes peanuts, cashews, and almonds to obtain 23 oz package worth 6.13 dollars. If peanuts, cashews, and almonds cost 11, 42, and 52 cents per oz respectively, and the weight of cashews in each package is equal to the weight of almonds, how much of each is in the package? ___oz of peanuts, ___oz of cashews, and ___oz of almonds.
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! x = oz of peanuts
y = oz of cashews
z = oz of almonds
---
x + y + z = 23
11x + 42y + 52z = 613
y = z
---
put the system of linear equations into standard form
---
x + y + z = 23
11x + 42y + 52z = 613
y - z = 0
---
copy and paste the above standard form linear equations in to this solver:
