Answer:
the answer is 11
Step-by-step explanation:
dont know
Answer:
16
Step-by-step explanation:
Let S is smart car and T is Toyota car
Case 1: 6 smart cars and 7 Toyota's = 6S + 7T
Case 2: 8 smart cars and 4 Toyota's
When 2 smart cars increase = 3 Toyota's cars descrease
So the ratio between them is:
2S = 3T
<=> S= 3/2T
so the maximum number of toyotas aboard the ferry
6*3/2T + 7T = 16 T
The simplified form of the expression is ![x^{-45} y^{-42}](https://tex.z-dn.net/?f=x%5E%7B-45%7D%20y%5E%7B-42%7D)
<h3>Simplifying an expression</h3>
From the question, we are to simplify the given expression
The given expression is
![\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B8%7Dy%5E%7B-26%7D%20%20%7D%7Bx%5E%7B14%7Dy%5E%7B-5%7D%20%20%7D%20%5Ctimes%20x%5E%7B-39%7D%20y%5E%7B-21%7D)
The expression can be simplified as shown below
![\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B8%7Dy%5E%7B-26%7D%20%20%7D%7Bx%5E%7B14%7Dy%5E%7B-5%7D%20%20%7D%20%5Ctimes%20x%5E%7B-39%7D%20y%5E%7B-21%7D)
![\frac{x^{8} \times x^{-39} \times y^{-26} \times y^{-21} }{x^{14} \times y^{-5} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B8%7D%20%5Ctimes%20x%5E%7B-39%7D%20%5Ctimes%20%20y%5E%7B-26%7D%20%5Ctimes%20%20y%5E%7B-21%7D%20%20%7D%7Bx%5E%7B14%7D%20%5Ctimes%20y%5E%7B-5%7D%20%20%7D)
![\frac{x^{8+-39} \times y^{-26+-21} }{x^{14} \times y^{-5} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B8%2B-39%7D%20%5Ctimes%20%20y%5E%7B-26%2B-21%7D%20%20%7D%7Bx%5E%7B14%7D%20%5Ctimes%20y%5E%7B-5%7D%20%20%7D)
![\frac{x^{8-39} \times y^{-26-21} }{x^{14} \times y^{-5} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B8-39%7D%20%5Ctimes%20%20y%5E%7B-26-21%7D%20%20%7D%7Bx%5E%7B14%7D%20%5Ctimes%20y%5E%7B-5%7D%20%20%7D)
![\frac{x^{-31} \times y^{-47} }{x^{14} \times y^{-5} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-31%7D%20%5Ctimes%20%20y%5E%7B-47%7D%20%20%7D%7Bx%5E%7B14%7D%20%5Ctimes%20y%5E%7B-5%7D%20%20%7D)
Then,
![\frac{x^{-31} }{x^{14} } \times \frac{ y^{-47} }{ y^{-5} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-31%7D%20%7D%7Bx%5E%7B14%7D%20%7D%20%5Ctimes%20%5Cfrac%7B%20y%5E%7B-47%7D%20%7D%7B%20y%5E%7B-5%7D%20%7D)
![x^{-31-14} \times y^{-47--5}](https://tex.z-dn.net/?f=x%5E%7B-31-14%7D%20%5Ctimes%20y%5E%7B-47--5%7D)
![x^{-31-14} \times y^{-47+5}](https://tex.z-dn.net/?f=x%5E%7B-31-14%7D%20%5Ctimes%20y%5E%7B-47%2B5%7D)
![x^{-45} \times y^{-42}](https://tex.z-dn.net/?f=x%5E%7B-45%7D%20%5Ctimes%20y%5E%7B-42%7D)
![x^{-45} y^{-42}](https://tex.z-dn.net/?f=x%5E%7B-45%7D%20y%5E%7B-42%7D)
Hence, the simplified form of the expression is ![x^{-45} y^{-42}](https://tex.z-dn.net/?f=x%5E%7B-45%7D%20y%5E%7B-42%7D)
