To find the mean just add all the numbers together then divide them by how many numbers there are.
To find the median you have to rewrite the list in numerical order then pick out the middle one which will be your answer
The mode is the number that is repeated more often than the others
For range pick out the largest and smallest number in the group and subtract those, the value you get will be the range :) Hope this helped

Step-by-step explanation:
1. -5 is 5 away from 0
2. indebted 34 dollars means to be in the negatives
3. -5.50 is 5.50 away from 0
4. 0-12 = -12
5. above sea level means to be positive
6. below sea level means to be negative
Answer:
$0.50x+5=30

X^2 + 4 = 0
Using the square root method, subtract 4 from both sides.
x^2 = -4
To clear the power of 2, take the square root of both sides.
x = + - square rot of (-4)
x = + - 2i
This is a complex answer because the radicand was a negative number.
x^2 - 6x + 1 = 0
I would use completing the square to solve this problem.
Subtract 1 from both sides.
x^2 - 6x = -1
When completing the square, take the b term (-6) and divide by 2 (-6/2= -3),
then square this number (9), add the number to both sides.
x^2 - 6x + 9 = -1 + 9
The left side is now a perfect square trinomial.
(x - 3)^2 = 8
To clear the power of 2, take the square root of both sides.
x - 3 = + - sqrt 8
add 3 to both sides and simplify sqrt 8
x = 3 + - 2sqrt2
