Answer:
5 candies
Step-by-step explanation:
Total of candy Sarah has = 25candies
If Sarah gave 2/5 of the candies to her sister, the total amount she gave her sister will be 2/5 of 25
2/5 of 25 = 10
The remaining candy left will be 25-10 which is 15.
If she gave 2/3 of amount left to her friend, the amount she gave her friend will be 2/3×15 = 10candies.
The amount of candy Sarah have left will be 15- 10 which is 5candies.
To check for symmetry on the x axis, replace y with –y
-y^2 –x(-y) =2
<span> Apply the product
rule, since the equation is not identical tot eh original equation it is not
symmetric about the x axis</span>
<span> Now do the same for y
axis by replacing x with –x</span>
<span> Again using product
rule the equations are not identical, so it is not symmetric about the y axis</span>
<span> To check the origin,</span>
<span> Replace both x &
y with –x & -y</span>
Again using product rule, the equations are not identical so
it is not symmetric about the origin
Answer:
x : -3
Step-by-step explanation:
1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)
2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)
3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)
4) -6x = 18 (divide the -6 on both sides)
5) x = -3
The gas exerts a pressure of 218.75 kPa when its volume is reduced to 2.0 L, following the behavior of an ideal gas.
Ideal gas behavior:
Suppose the initial volume of carbon dioxide gas is V = 3.5l
Initial pressure is P = 125 kPa
Since the volume is reduced to 2.0l, the final volume is shown as V'= Will be done. 2L
The final pressure of the gas is P'.
We consider the behavior of gas to be ideal. From the ideal gas equation, it becomes as follows.
PV = P'V'
125 × 3.5 = P'× 2
P'= 218.75 kPa
Therefore, the final pressure is 218.5 kPa.
