Answer:
the distance between two numbers and on the number line is . Note that the distance between two numbers is always positive, no matter the order. But the difference can be positive or negative, depending on the order.
Step-by-step explanation:
the distance between two points on a line is abs(x1-x2) which is a symmetric function abs(y)=abs(-y) so abs(x1-x2)=abs(-(x1-x2))=abs(x2-x1) so the order does not matter since you take abs after the subtraction.

Answer:
what do you need help with?
Step-by-step explanation:
7z - 1/2 = 3z - 2
Subtract 3z to both sides:
4z - 1/2 = -2
Add 1/2 to both sides:
4z = -1 1/2
Divide 4 to both sides:
z = -0.375 or -3/8
