The picture is completely black I’m not sure if that’s what you’re trying to fix but I think you didn’t uploads it correctly.
A-
3x+6=18
3x=18-6
3x=12
X=4
A is the correct answer
-36-8 = -44
-36+(-8) = -44
third option
Question 7: $3945
78,900÷100×5= 3,945
or 789,00×0.05= $3,945
Question 8: I think it may be $675.46 ( but I'm not sure)
$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12
$1010÷12= $84.20
also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.
$938÷12=$78.20
and in order to find out her combined monthly payment we need to add them all together
$513.12+$84.16+$78.16= $675.46
Question 9: is False
Question 10: I don't know
Hope this helps
