Answer:
You should make 250 quarts of Creamy Vanilla and 200 of Continental Mocha to use up all the eggs and cream.
Step-by-step explanation:
This problem can be solved by a first order equation
I am going to call x the number of quarts of Creamy Vanilla and y the number of quarts of Continental Mocha.
The problem states that each quart of Creamy Vanilla uses 2 eggs and each quart of Continental Mocha uses 1 egg. There are 700 eggs in stock, so:
2x + y = 700.
The problem also states that each quart of Creamy Vanilla uses 3 cups of cream and that each quart of Continental Mocha uses 3 cups of cream. There are 1350 cups of cream in stock, so:
3x + 3y = 1350
Now we have to solve the following system of equations
1) 2x + y = 700
2) 3x + 3y = 1350
I am going to write y as function of x in 1) and replace it in 2)
y = 700 - 2x
3x + 3(700 - 2x) = 1350
3x + 2100 - 6x = 1350
-3x = -750 *(-1)
3x = 750
x = 250
You should make 250 quarts of Creamy Vanilla
Now, replace it in 1)
y = 700 - 2x
y = 700 - 2(250)
y = 700 - 500
y = 200.
You should make 200 quarts of Continental Mocha
Answer will be no A I think that
For this case we must simplify the following expression:
![\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}}](https://tex.z-dn.net/?f=%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%7D)
Multiplying the numerator and denominator by![(\sqrt [3] {9}) ^ 2](https://tex.z-dn.net/?f=%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202)
![\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}} * \frac {(\sqrt [3] {9}) ^ 2} {(\sqrt [3] { 9}) ^ 2} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%7D%20%2A%20%5Cfrac%20%7B%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%28%5Csqrt%20%5B3%5D%20%7B%209%7D%29%20%5E%202%7D%20%3D)
We rewrite:
![\frac {\frac {6-3 \sqrt [3] {6}} * (\sqrt [3] {9}) ^ 2} {\sqrt [3] {9} * (\sqrt [3] {9 }) ^ 2} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%5Cfrac%20%7B6-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%7D%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%5Csqrt%20%5B3%5D%20%7B9%7D%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%20%7D%29%20%5E%202%7D%20%3D)
By properties of powers we have that:
![a ^ m * a ^ n = a ^ {m + n}\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {(\sqrt [3] {9}) ^ 3} =\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {9} =](https://tex.z-dn.net/?f=a%20%5E%20m%20%2A%20a%20%5E%20n%20%3D%20a%20%5E%20%7Bm%20%2B%20n%7D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%203%7D%20%3D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%28%5Csqrt%20%5B3%5D%20%7B9%7D%29%20%5E%202%7D%20%7B9%7D%20%3D)
We rewrite, moving the exponent within the radical:
![\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {9 ^ 2}} {9} =\\\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {81}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B9%20%5E%202%7D%7D%20%7B9%7D%20%3D%5C%5C%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B81%7D%7D%20%7B9%7D%20%3D)
We can rewrite
![\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {3 * 3 ^ 3}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%20%5Csqrt%20%5B3%5D%20%7B3%20%2A%203%20%5E%203%7D%7D%20%7B9%7D%20%3D)
We simplify:
![\frac {(6-3 \sqrt [3] {6}) * 3 \sqrt [3] {3}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B%286-3%20%5Csqrt%20%5B3%5D%20%7B6%7D%29%20%2A%203%20%5Csqrt%20%5B3%5D%20%7B3%7D%7D%20%7B9%7D%20%3D)
We apply distributive property:
![\frac {18 \sqrt [3] {3} -9 \sqrt [3] {18}} {9} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B18%20%5Csqrt%20%5B3%5D%20%7B3%7D%20-9%20%5Csqrt%20%5B3%5D%20%7B18%7D%7D%20%7B9%7D%20%3D)
Simplifying we finally have:
![2 \sqrt [3] {3} - \sqrt [3] {18}](https://tex.z-dn.net/?f=2%20%5Csqrt%20%5B3%5D%20%7B3%7D%20-%20%5Csqrt%20%5B3%5D%20%7B18%7D)
Answer:
![2 \sqrt [3] {3} - \sqrt [3] {18}](https://tex.z-dn.net/?f=2%20%5Csqrt%20%5B3%5D%20%7B3%7D%20-%20%5Csqrt%20%5B3%5D%20%7B18%7D)
