In pig race, your pig gets a head start of 3 feet and is running at a rate of 2 feet per second. your friend's pig is also running at a rate of 2 feet per second. a system of linear equations that represent this situation is y=2x+3 and y=2x. will your friend's pig catch up to your pig? explain

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
