Answer: 3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. Find the prime factorization of 27:
or 
2. The index of the radical is 3, therefore, you have rewrite it as following:
![\sqrt[3]{27}=\sqrt[3]{3^{3}}=3^{\frac{3}{3}}=3^{1}=3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D%3D%5Csqrt%5B3%5D%7B3%5E%7B3%7D%7D%3D3%5E%7B%5Cfrac%7B3%7D%7B3%7D%7D%3D3%5E%7B1%7D%3D3)
3. Therefore, as you can see, the answer is 3.

<span>To find: Cost of backcover.
Solution:
Let the cost of backcover be x.
Then,
56 = 2x - 24
56+24 = 2x
80 = 2x
80 / 2 = x
x = 40
The cost of backpack is $40.</span>
Answer:
Step-by-step explanation:
Y = -x -1..........(1)
y = -2x + 7....(2)
Equating the two equations
-x -1 = -2x + 7
-x + 2x = 7+1
x = 8
Putting x in (1)
y = -8 - 1
y = -9
