Answer:
1.) -2
2.) -5
3.) 1
4.) 3
5.) -11/10
6.) 3.5
Step-by-step explanation:
1.) 7 - 9
7 - 9 = -2
Check....
-2 + 9 = 7
9 - 2 = 7
So you know its correct
__________________________________________________________
2.) -2 - 3
2 negatives added together, will result in a bigger negative number
-2 - 3 = -5
Check....
-5 + 3 = -2
-5 + 2 = -3
So you know its correct
__________________________________________________________
3.) -5 - (-6)
When 2 negatives are together -(-) that means it will result in a positive number.
-5 + 6 = 1
Check
1 - 6 = -5
5 + 1 = 6
So now you know its correct
__________________________________________________________
4.) -1 - (-4)
2 negatives being subtracted together will result in a positive number.
-1 + 4 = 3
3 - 4 = -1
4 - 1 = 3
So now you know its correct
__________________________________________________________
5.)
-2/5 - 7/10
I need to find a common denominator and in this case it can be 10
-2*2/5*2 = -4/10
-4/10 - 7/10
2 negatives being added together will result in a bigger negative number
-11/10
Check
-11/10 + 4/10 = -7/10
-11/10 * 7/10
So now you know its correct
__________________________________________________________
6.) -3.6 - (-7.1)
2 negatives being subtracted will result in a positive number
-3.6 + 7.1 = 3.5
Check...
7.1 - 3.5 = 3.6
3.6 + 3.5 = 7.1
So now you know its correct
Hope this helped!
