Answer:A and E
Step-by-step explanation:Have an amazing weekend!
So these are our two equations: 
Before we can use elimination, subtract y on both sides of the first equation: 
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get
. From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, x = 3 and y = 6.</u>

Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4
