Answer:
Price of each phone: 
Price of each accessory: 
Step-by-step explanation:
Let be "p" the price in dollars of each phone and "a" the price in dollars of each accessory.
Set up a system of equations:

You can use the Elimination Method to solve the system.
Multiply the second equation by -2 and add both equations:

Substitute the value of "a" into the first equation and solve for "p":

The expression is undefined when C, x = 9.
The way that this expression can be undefined is if the denominator is 0 (dividing by 0 is undefined). To make the denominator 0, that means that 9 - x =0. That means that x = 9. So, when x = 9, the denominator is zero, meaning that the expression is undefined when C, x = 9.
Answer:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b.
Answer: approximately 5.5814 calories
==================================
We start off with this ratio
4.3 ounces : 24 calories
Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side
4.3 ounces : 24 calories
4.3/4.3 ounces : 24/4.3 calories
1 ounce : 5.5814 calories
This value is approximate to four decimal places.
