Answer 2

It seems like you have provided four mathematical expressions involving absolute values. To solve these equations, we need to consider both the positive and negative cases for the absolute value. Here are the solutions for each of the given equations:

1. $|x| = 1.2$

In this case, $x$ can be either 1.2 or -1.2.

2. $\frac{225}{|x|} = 1.5$

To solve for $|x|$, first, divide 225 by 1.5:

$|x| = 150$

$x$ can be either 150 or -150.

3. $\frac{-4.84}{|x|} = -4.4$

First, multiply both sides by $|x|$ to get rid of the fraction:

$-4.84 = -4.4 |x|$

Now, divide both sides by -4.4:

$|x| = \frac{4.84}{4.4} \approx 1.1$

$x$ can be either 1.1 or -1.1.

4. $79 + \frac{4}{|x|} = 81.8$

First, subtract 79 from both sides:

$\frac{4}{|x|} = 2.8$

Now, multiply both sides by $|x|$ to get rid of the fraction:

$4 = 2.8 |x|$

Divide both sides by 2.8:

$|x| = \frac{4}{2.8} \approx 1.43$

$x$ can be either 1.43 or -1.43.
