6. Arrange the following masses from small to large:
0.065kg; 20kg; 45mg; 200g; 2500g; 0.67g; 2000mg​

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.

C. y = -3, the line lies on the y-axis and is on -3
