Answer 1

`absA<=7.3`

Explanation:

The answer is `absA<=7.3`. To show this, remember that
absolute value inequalities can be written as two inequalities.

Write the first as given, but without the absolute value sign.
`color(red)(A<=7.3)`

Write the second with a "flipped" direction of the inequality and a negative on the right side.
`color(blue)(A>=-7.3)`, which can also be written as `color(blue)(-7.3<=A)`
Note that the 2nd is just a "flipped" version of the 1st.

Combining `color(blue)(-7.3<=A)` and `color(red)(A<=7.3)` gives

`color(blue)(-7.3<=)color(purple)Acolor(red)(<=7.3)`
