To solve this problem you must apply the proccedure shown below:
1. Let's call:
the number of roses and
the number of lilies.
2. You must make a system of equation based on the information given in the problem above:
![1) 1.75x+2y=21.75\\ 2) x+y=12](https://tex.z-dn.net/?f=%201%29%201.75x%2B2y%3D21.75%5C%5C%202%29%20x%2By%3D12%20)
3. Use the method of substitution. First, solve for
in the second equation, then substitute it into the first equation, and then solve for
:
![x=12-y\\ 1.75(12-y)+2y=21.75\\ y=3](https://tex.z-dn.net/?f=%20%20x%3D12-y%5C%5C%201.75%2812-y%29%2B2y%3D21.75%5C%5C%20y%3D3%20)
4. Now, substitute
into the second equation:
![x+3=12\\ x=9](https://tex.z-dn.net/?f=%20x%2B3%3D12%5C%5C%20x%3D9%20)
Therefore, the answer is:
roses and
lilies.
This is false because 2(7)+0.8/0.2=56 and 22* -4 is equal to -88 and -88 is not equal to 56
312 the answer is 312 a foot is 12 inches long so 12x26 =312
