X = 1, since they intersect at (1,6) and are thus equal at that point
17) from least to greatest
1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, 1
X=11
All you have to do is add 5 to both sides and then divide by 5 on both sides
(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
The mean is the average.
To solve for the average we add all the numbers up and divide by how many numbers there are.
21, 23, 25, 25, 26, 28, 28, 28, 31, 33.
268 total, now divide by how many numbers there are.
268/10
Your mean is 26.8
