When the temperature is constant, the pressure of a given mass of gas is inversely proportional to its volume. Given that the pressure is 75 cm of mercury when the volume is 150 cm', find the pressure when the volume is 100 cm

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
