Step-by-step explanation:
10. [-19-(-20) - (-34)] ÷ (-6)
= (-19+20+34) ÷ (-6)
= 35 ÷ (-6)
= -5.83
12. [-18 - (-66) -22] × 2
= [-18+66-22] × 2
= 26 × 2
= 52

First rewrite each number in scientific form
Answer:
-1
Step-by-step explanation:
7+(-1)= 6
6/3 = 2
There are no other solutions I can find to it. It says sum but technically you can add a negative number.
Don´t listen to me if you think that I am wrong. But I hope this helps!!
