Answer: Use order of operations (PEMDAS). Answer is 45.72.
Step-by-step explanation:
First, solve inside parenthesis:
(5.25*1 1/5 - 4.5*4/5)
Convert 1 1/5 into decimal. It will be easier. 1 1/5 is the same as 1.2
Do multiplication and division first.
5.25*1.2 = 6.3
Now it looks like: (6.3 - 4.5*4/5)
Convert 4/5 to a decimal: 4/5 = 0.8
(6.3 - 4.5*0.8)
Multiply 4.5*0.8 = 3.7
Subtract (6.3 - 3.7) = 2.6
Now the full equation is: 19.6*2 1/5 + (2.6)
2 1/5 as a decimal: 2.2
Multiply 19.6*2.2 = 43.12
Now the equation is: 43.12 + 2.6
Add 43.12 + 2.6 = 45.72

Answer:</h2><h2>When the volume is 60 cubic centimeters, the pressure is 4.26 pounds</h2>
Step-by-step explanation:
Let V be the volume of the gas and P be its pressure.
The volume of a gas in a container varies inversely with the pressure on the gas:
V = k/P
VP = k, where k represents constant temperature
Given the volume is 32 cubic centimeters at a pressure of 8 pounds
where V1 = 32, P1 = 8 ... (1)
The pressure when the volume is 60 cubic centimeters,
V2 = 60, P2 = ? ... (2)
Comparing eq (1) and (2)
V1 P1 = V2 P2
32 (8) = 60 (P2)
256 = 60 (P2)
P2 =
P2 = 4.26 pounds
First subtract 24 from 45 to get 21. Then add 7 to 21 to get 28.
3x = 16 you need to get 3x by itself so you can divide so add the 3 to the other side
