Please help me out with this quiz , I am really struggling I’ll mark you :)
Also pls show work

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!

Have a day!
