Answer:

Monthly cost of cell phone for 0 minutes is $19.95 and for 40 minutes of talk is $21.95. It means that average rate of change ( increase of monthly cost for each minute of talk time ) is: ARC = ( 21.95 - 19.95 ) / ( 40 - 0 ) = 2.00 / 40 = $0.05. Answer: C ) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.

After solving the system x+2y=10 and x-2y=2. What is the sum of x+y equal to?
Masja [62]

Answer:

The sum of x and y is 8.

Step-by-step explanation:

x+2y=10

x-2y=2

------------

2x = 12, so x = 6.  Substituting 6 for x in the 2nd equation, we get:

6 - 2y = 2, or

4 = 2y, or y = 2.  The solution is therefore (6, 2).

The sum of x and y is 6 + 2 = 8 (answer)

What is 5 8/5 in a whole number
Fantom [35]
Assuming that the number you are attempting to write is 5 8/5, you're whole number would be 6 3/5.

However, if the number is actually 58/5, then the whole number would be 11 3/5.

Here's how to find the answer:

For 5 8/5, you must find how many times 5 goes into the numerator since 5/5 is one whole number. However, there will sometimes be remainders as presented in this question, thus leaving you with another fraction which is 3/5.

Hope this helps!
