A person drove at a speed of 28 miles per hour on a back road during a recent trip. They can drive the same distance at 44 mph on the interstate in three hours less. What is the distance they drove on the back road?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

The party planning committee has to determine the number of tables needed for an upcoming event. if a square table can fit 8 people and a round table can fit 6 people, the equation 150 = 8x + 6y represents the number of each type of table needed for 150 people.

Graph the system of equations. {6x−4y=−244x−8y=−32 use the line tool to graph the lines.
