4x = -12
First, divide both sides by 4. / Your problem should look like:
Second, since 4 goes into 3 to get 12, simplify it by 3. / Your problem should look like:

Answer:
x = -3

It is called a spring tide
Answer:
8.68 L is the new volume
Explanation:
You use Boyle's law for this.

= first pressure
= second pressure
= first volume
= second volume
Convert pressure from atm to mmHg (use same units):
5.97 x 760 = 4537.2 -> 4.54 x 10³
...maintain 3 significant figures in calculation, and round as needed...
(4.54 x 10³ mmHg)(2.79 L) = (1460 mmHg)(
)
(4.54 x 10³ mmHg)(2.79 L) / (1460 mmHg) =
= 8.68 L
Hope this helps :)
