Answer:
4.66 (4 2/3, 14/3)
Step-by-step explanation:
You solve it just like you would with an equation.
Answer:
3
Step-by-step explanation:
1/4 = 2/8
With 7/8 pounds of meat, you can make 3 patties (6/8) and have 1/8 pound leftover
The length of the base 3 times the width. And we need to express the surface. I'm assuming the surface of the base. So, to get the area of the base, multiply w * l.
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
![5x - 4y = -3](https://tex.z-dn.net/?f=5x%20-%204y%20%3D%20-3)
![5x - 4(3x-5) = -3](https://tex.z-dn.net/?f=5x%20-%204%283x-5%29%20%3D%20-3)
![5x -12x+20=-3](https://tex.z-dn.net/?f=5x%20-12x%2B20%3D-3)
_______________
![5x-12x=-23](https://tex.z-dn.net/?f=5x-12x%3D-23)
![-7x=-23](https://tex.z-dn.net/?f=-7x%3D-23)
___ ____
![-7](https://tex.z-dn.net/?f=-7)
(rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
![y = 3x-5](https://tex.z-dn.net/?f=y%20%3D%203x-5)
![y = 3(3.29)-5](https://tex.z-dn.net/?f=y%20%3D%203%283.29%29-5)
![y = 9.87-5](https://tex.z-dn.net/?f=y%20%3D%209.87-5)
![y = 4.87](https://tex.z-dn.net/?f=y%20%3D%204.87)
So, your final answer would be (3.29, 4.87).
