You need to subtract 638 and 62 and that will give 576
To find which equation is equivalent, we simplify the equations.
3x + 6y – 3z = 6
<span>(3x + 6y – 3z = 6)1/3
</span>x + 2y - z = 2 ------------> not equal
(4x + 12y – 4z = 12)1/4
x + 3y - z = 3<span>------------> equal</span>
(2x + 4y – 2z = 8)1/2
x + 2y - z = 4 ------------> not equal
2x + 3y – 4z = 12 ------------> not equal
Answer:
The maximum number of vases that the dance committee can buy is ![15\ vases](https://tex.z-dn.net/?f=15%5C%20vases)
Step-by-step explanation:
Let
x------> the number of vases
we know that
![3x+30\leq 75](https://tex.z-dn.net/?f=3x%2B30%5Cleq%2075)
Solve for x
![3x\leq 75-30](https://tex.z-dn.net/?f=3x%5Cleq%2075-30)
![3x\leq 45](https://tex.z-dn.net/?f=3x%5Cleq%2045)
![x\leq 15\ vases](https://tex.z-dn.net/?f=x%5Cleq%2015%5C%20vases)
The maximum number of vases that the dance committee can buy is ![15\ vases](https://tex.z-dn.net/?f=15%5C%20vases)
