Answer:
Solution x = - 1
Step-by-step explanation:
3 / (2x+1) = 9 / 3x
Cross multiply
3(3x) = 9(2x + 1)
Distributive property
9x = 18x + 9
Subtract 18x from both sides
-9x = 9
Divide both sides by -9
x = -1
Answer:
x= -8 BDC= 68
EXPLANATION:
They create a straight angle which is always equal to 180. this means you must add both equations and set them equal to 180.
Answer:
78.5 cm. cubed
Step-by-step explanation:
Answer:
The final volume is 320 mL at pressure of 100 kPa.
Step-by-step explanation:
Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,
![V\propto \dfrac{1}{P}\\\\P_1V_1=P_2V_2](https://tex.z-dn.net/?f=V%5Cpropto%20%5Cdfrac%7B1%7D%7BP%7D%5C%5C%5C%5CP_1V_1%3DP_2V_2)
Let
![V_1=40\ mL\\\\P_1=80\ kPa\\\\P_2=100\ kPa](https://tex.z-dn.net/?f=V_1%3D40%5C%20mL%5C%5C%5C%5CP_1%3D80%5C%20kPa%5C%5C%5C%5CP_2%3D100%5C%20kPa)
We need to find
. Using above equation, we get :
![V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{400\times 80\times 10^3}{100\times 10^3}\\\\V_2=320\ mL](https://tex.z-dn.net/?f=V_2%3D%5Cdfrac%7BP_1V_1%7D%7BP_2%7D%5C%5C%5C%5CV_2%3D%5Cdfrac%7B400%5Ctimes%2080%5Ctimes%2010%5E3%7D%7B100%5Ctimes%2010%5E3%7D%5C%5C%5C%5CV_2%3D320%5C%20mL)
So, the final volume is 320 mL at pressure of 100 kPa.
