Answer:
-9+5=-4
Step-by-step explanation:
a negative times a negative is always a positive.
Answer:
2x-5= -20
move -5 to the other side
sign changes from -5 to 5
2x-5+5= -20+5
2x= -15
divide by 2 for both sides
2x/2= -15/2
cross out 2 and 2, divide by 2 and 2 and then becomes x
x= -15/2
So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.

here's the answer to your question
I got 6x+3
The three equations are:
(2x-6) + (3x+1) + (x+8) =perimeter
2x+3x+x/1x=6x
-6+1+8= 3
