Answer:
m=-7
Step-by-step explanation:
You begin with the equation:
2m-6=4m+8
The first step of this would be to subtract 2m from both sides. This is the subtraction property of equality.
-6=2m+8
The next step would be to subtract 8 from both sides. This is the subtraction property of equality.
-14=2m
Next, divide both sides by 2. This is the division property of equality.
-7=m
The final step would be the symmetric property of equality.
m=-7
Therefore your proof would have the steps:
subtraction property of equality
subtraction property of equality
division property of equality
symmetric property of equality

Answer:
50%
Step-by-step explanation:
To calculate the percentage of increase, what we must do divide the two quantities, in this way we will be able to know how bigger they are from each other. So:
9000/6000 = 1.5
Now, we subtract those from 1, which would be 100%
1.5 - 1 = 0.5
therefore the increase was 50%
