Can you please answer and show your work! thank you so much :)

1: -7

2: -7

3:-7

4: 8

5: 8

6: 8

Step-by-step explanation:

for the first one, you do 6-1=5 and then times that by 2 and then simplify that to get -7. for the second one, you do which is 8+4=12, and divide 24 by that to get 2 and minus nine to get -7. for the 3rd one, you do +9 first (16+9)= 25, and subtract 39 from that to get 14, then do 4-5=-1 *2=-2, which gets you -7. for 4 , you do 81-25= 56 over 10+8-11=7 which gets you 8. for 5, you do 36-20=16  in parentheses first and then divide 48 by that to get 3 and subtract that to get 8. last, for 6, you do 22-14 to get you 8
