Answer:
x=-12
Steps:
Step 1: Flip the equation
x-20=-32
Step 2: Add 20 to both sides.
x-20+20=-32+20
x=-12
The conversion is 9*9=81
The conversion is true
Well, this is a stem and leaf problem.
The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42.
In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers).
The mean is 32.
The median is the middle number, or 31.
