Answer:
8 nickels
Step-by-step explanation:
Let n be the number of nickels.
4: (2+ 6 + 4 + n) = 1:5
4÷(12 + n) = 1÷5
4 x 5 = 1 x (12 + n)
20 = 12 + n
n = 8
Answer:

Step-by-step explanation:
Given function is,
f(x) = ![\sqrt[3]{8x}+4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%2B4)
To find the inverse of this function,
Rewrite the function as a equation,
y = ![\sqrt[3]{8x}+4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%2B4)
Interchange x by y and y by x,
x = ![\sqrt[3]{8y}+4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D%2B4)
Now solve this equation for y,
x - 4 = ![\sqrt[3]{8y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D)
(x - 4)³ = ![(\sqrt[3]{8y})^3](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B8y%7D%29%5E3)
(x - 4)³ = 8y
y = 
Now convert the equation into function,
