Answer:
6) 9
7) 9
8) 10
9) 13
10) negative
Step-by-step explanation:
6) The |#| means absolute value (the value of how far away a number is from 0). Any number in that position will be positive (e.g., |-9| is 9).
|-5|+4
5+4
9
--------------------------------------------------------------------------------------------------------------
7) A negative divided by a negative is always a positive.
-99/(-11)
99/11
9
--------------------------------------------------------------------------------------------------------------
8) This is a bit confusing. Anything within |#| must be solved before you change it into AVF (absolute value form).
|(-6)-4|
|-10|
10
--------------------------------------------------------------------------------------------------------------
9) Subtracting a negative makes it positive.
4-(-9)
4+9
13
--------------------------------------------------------------------------------------------------------------
10) 1 times -1 equals -1
2 times -2 equals -4
3 times -3 equals -9
And so on.
--------------------------------------------------------------------------------------------------------------
Hope this helped!
