We will have the following:
First, we solve both equations for y, that is:


&


From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.
ok
we are ask for measuring of center
there are 3 different measures
mode, when the data value occurs the most frequently
median, is the data value in the middle of a sorted list of data
mean is the average of the numbers
so the answer is A) mean and median
Answer:

Step-by-step explanation:

220pm=10w (people*minutes)
w=22pm
14w=308pm
308pm/14p=22m
So it would take 22 minutes for 14 people to paint 14 walls.
