29/5 should be the correct answer
Answer:
x = 6, y = -8
Step-by-step explanation:
First we take the equations side by side and put them like this:
6x + 2y = 16
+ 2x - 2y = 32
8x = 48
Then solve for x.
x = 6
Then insert x back into either equation
2(5) - 2y = 32
10 - 2y = 32
solve for y,
y = -10
The answer to that would be D!
The mean is
7+10+13+4+12+21+10+3/8
=80/8
= 10

Answer:
8.11
Step-by-step explanation:
You round it up because the 3rd number (thousandths) is 5 or above, and since it's 7 you round that up and drop off the last number.
