First is pears ,next is apple, and the last is oranges. 3,900, 3800, 3500. I hope that this helps.
Answer:
7x-20=2x-3(3x+2)
We move all terms to the left:
7x-20-(2x-3(3x+2))=0
We calculate terms in parentheses: -(2x-3(3x+2)), so:
2x-3(3x+2)
We multiply parentheses
2x-9x-6
We add all the numbers together, and all the variables
-7x-6
Back to the equation:
-(-7x-6)
We get rid of parentheses
7x+7x+6-20=0
We add all the numbers together, and all the variables
14x-14=0
We move all terms containing x to the left, all other terms to the right
14x=14
x=14/14
x=1
Step-by-step explanation:
<h2>Hello!</h2>
The answer is:
The first measurement of volume is equal to 835.23 mL.
<h2>Why?</h2>
Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.
So, we Boyle's Law equation states that:
![P_{1}V_{1}=P_{2}V_{2}](https://tex.z-dn.net/?f=P_%7B1%7DV_%7B1%7D%3DP_%7B2%7DV_%7B2%7D)
Where,
![P_1=FirstPressure\\V_1=FirstVolume\\P_2=NewPressure\\V_2=NewVolume](https://tex.z-dn.net/?f=P_1%3DFirstPressure%5C%5CV_1%3DFirstVolume%5C%5CP_2%3DNewPressure%5C%5CV_2%3DNewVolume)
Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:
![P_{1}V_{1}=P_{2}V_{2}\\\\V_{1}=\frac{P_{2}V_{2}}{P_{1}}](https://tex.z-dn.net/?f=P_%7B1%7DV_%7B1%7D%3DP_%7B2%7DV_%7B2%7D%5C%5C%5C%5CV_%7B1%7D%3D%5Cfrac%7BP_%7B2%7DV_%7B2%7D%7D%7BP_%7B1%7D%7D)
So, substituting the given information and calculating, we have:
![V_{1}=\frac{8.59atm*527mL}{5.42atm}](https://tex.z-dn.net/?f=V_%7B1%7D%3D%5Cfrac%7B8.59atm%2A527mL%7D%7B5.42atm%7D)
![V_{1}=\frac{4526.93atm.mL}{5.42atm}=835.23mL](https://tex.z-dn.net/?f=V_%7B1%7D%3D%5Cfrac%7B4526.93atm.mL%7D%7B5.42atm%7D%3D835.23mL)
Hence, the first measurement of volume is equal 835.23 mL.
Have a nice day!
