Celsius, Fahrenheit, Kelvin? One’d colder than the other. Unless ur looking for a detailed answer lol.
No actually you can just multiply both sides of the equation by 2 and get y-4=20. then add 4 to both sides to get y=24.
2.74 liters since 1000mL is a liter.
The answer would be $102.14 if you divide 255.35 by 5 then multiply it by 2, you'll get 102.14
255.35 divided by 5 = 51.07 x 2 = 102.14
Hope this helps! ;)
