its .86 which is closer to .87
so choose the first one
Start by dividing both sides by 2 to get

. Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us

. Rewriting this in exponential form is

. That means that x = 8. Not negative, only positive.
Answer:
The new pressure of the gas is 42 pounds per square inches.
Step-by-step explanation:
When the temperature remains constant, the volume of a gas is inversely proportional to the pressure of the gas.

We can rewrite the above equation is
[at constant temperature]
At a pressure of 14 pounds per square inches, a balloon is filled with 93 cubic inches of gas.
The volume of the gas is decreased to 31 cubic inches.
Here,
= 93 cubic inches,
= 14 pounds per square inches,
=31 cubic inches,
= ?




pounds per square inches
The new pressure of the gas is 42 pounds per square inches.
