Answer:
-7<x<-3
Step-by-step explanation:
separate into two inequalities:
3x+15>-6
3x+15<6
solve inequalities:
3x>-21........3x<-9
x>-7.............x<-3
Henry will get $15.77 back.
20 - 4.23 = 15.77
-9
The sum of -2 and -7 is given as follows;
-2 + (-7)
In mathematical operations, + * - is -.
So we have;
-2 - 7
This gives us: -9
