NEED HELP. LOOK AT PIC.
Sonja [21]

Answer:

x = 8/3

y = 7/3

Step-by-step explanation:

In a parallelogram the diagonals bisect each other.

So 2x = y + 3

x + y = 5

Then you set them up to do combination/elimination to solve for the two variables.

2x-y = 3

Then you add the two equations together

3x =  8

Solve for x

x = 8/3

Then solve for y by plugging it into a equation

x + y = 5

8/3 + y = 5

8/3 - 5 = -y

8/3 - 15/3 = -y

-7/3 = -y

y = 7/3

According to Boyle’s law, PV= K, what was the volume at the time of the first measurement given the following information? Round
Temka [501]
<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}

Where,

P_1=FirstPressure\\V_1=FirstVolume\\P_2=NewPressure\\V_2=NewVolume

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}}

So, substituting the given information and calculating, we have:

V_{1}=\frac{8.59atm*527mL}{5.42atm}

V_{1}=\frac{4526.93atm.mL}{5.42atm}=835.23mL

Hence, the first measurement of volume is equal 835.23 mL.

Have a nice day!

jarptica [38.1K]

Answer:

Week and a day

Step-by-step explanation:

You have $30, you save $5 each week and your aunt gives you an extra $10. Equaling out to $15 per week. Since the bike costs $155.75, you subtract your $30, coming out to 125.75 then you divide it by 15 which is 8 days
