What property of equality is 4x+10=22

This is the property of solve for x.

Step-by-step explanation:

X=3

11, 12, 15, 16, 20, 20, 25
Mean: 17

The range is 25-11 = 14 (the numbers in bold)

The interquartile range is 20-12=8 (the numbers underlined)

The mean absolute deviation is: 4; this is found by finding how far each number is from 17 (mean): 6,5,2,1,3,3,8  (28) and dividing by 7.

Part B:

The prices vary by no more that $14 (range).

The middle half of the prices vary by no more than $8 (IQR).

The admission prices differ from the mean price by an average of $4 (MAD).
