3x+4y=23
2y-x= -19/ multiply -2
4y + 3x = 23
-4y - 2x = 38
_______________
X = 61
2y - x = -19
2y - 61 = -19
2y = 61 -19
2y = 42
Y = 21
Answer:
Certain information about these bombs are not readily available on the Internet. The marathon bombers had to have carefully their attack since both bombs exploded around the same time.
Explanation:
The observation that is inconsistent with the ideal gas equation is; "When temperature is held constant and volume increases, the pressure increases."
Boyle's law describes the relationship between the pressure and volume of ideal gas. Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Hence, the statement that "When temperature is held constant and volume increases, the pressure increases." does not agree with Boyle's law therefore it is inconsistent with the ideal gas law.
