Two friends, William and Brayden, had just bought their first cars. The equation y = 41.5x represents the number of miles, y, that Brayden can drive his car for
every a gallons of gas. William uses 11 gallons of gas to drive 215.6 miles in his car.
How much farther can Brayden's car travel on one gallon of
gas than William's car?

Aman steps out of a plane at a height of 4,000m above the ground falls 2,000m very quickly and then opens his parachute and slowly falls the remaining 2000m to the ground what height above the ground would be the best choice for a reference point

If 1/√5+1/√5+1=p+q√r , find the values of p, q and r

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
