Answer:

1.33333333333 cm

Step-by-step explanation:

It's pretty simple:

Based on the question, we know that 24cm = 18 miles

Therefore we can do a three simple rule

If 24 cm = 18 miles

x cm = 1 mile

x = $\frac{24 * 1}{18}$

x = $1.33333333333 cm$

Answer:

B. |ax + b| ≥ c, where c is greater than zero.

Step-by-step explanation:

Given two inequalities $x\le 2$ and $x\ge 4.$

First, make the number in right parts of both inequalities the same by absolute value. You can reach this by subtracting 3:

$x\le 2\\ \\x-3\le 2-3\\ \\x-3\le -1$

and

$x\ge 4\\ \\x-3\ge 4-3\\ \\x-3\ge 1$

The two inequalities $x-3\le -1$ and $x-3\ge 1$ are equivalent to the ineguality

$|x-3|\ge 1$

Thus, option B is correct option.
