-6y + 11x = -36....multiply by 4
-4y + 7x = -24....multiply by -6
-----------------
-24y + 44x = - 144 (result of multiplying by 4)
24y - 42x = 144 (result of multiplying by -6)
----------------add
2x = 0
x = 0
-4y + 7x = -24
-4y + 7(0) = -24
-4y = -24
y = -24/-4
y = 6
solution is (0,6)
Answer: 95%
Explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%
The statements which is evident that gases do not always behave ideally include the following:
- It is impossible to compress a gas enough so that it takes up no volume.
- CO2 gas becomes dry ice (solid co2) at 1 atm and –78.5∘c.
- At 4 k and 1 atm, helium is a liquid.
<h3>What is an Ideal gas?</h3>
This is the type of gas in which all collisions between atoms or molecules are perfectly elastic.
It has no intermolecular attractive force and not all gases behave ideally as can be seen in the above examples.
