A vehicle with an empty fuel tank has a mass of 1050 kg. One litre of petrol
has a mass of 737 g. What is the
minimum amount of whole litres of
petrol that would cause the total mass
to exceed 1100 kg?​

How can you tell when x and y are not directly proportional?

(60 points) explain this in detail

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
