Answer:
40 units
Step-by-step explanation:
On the number line, the distance between x and y is given by
|x-y|.
To find the distance between -70 and -30 on the number line, we find the absolute value of their difference.
Therefore the distance between -70 and -30 on the number line is 40 units.

Step-by-step explanation:
<u>Step 1: Define</u>
-6 = b8
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: -6 = 8b
- Divide 8 on both sides: -6/8 = b
- Rewrite: b = -6/8
- [Fraction] Simplify: b = -3/4
<u>Step 3: Check</u>
<em>Plug in b into the original equation to verify it's a solution.</em>
- Substitute in <em>b</em>: -6 = (-3/4)8
- Multiply: -6 = -24/4
- Divide: -6 = -6
Here we see that -6 does indeed equal -6.
∴ b = -3/4 is the solution to the equation.
