A train travels 250 miles at a constant speed (x), in miles per hour.
Enter an equation that can be used to find the speed of the train, if the time to travel 250 miles is 5 hours.

Juan buys peaches and grapefruit at the store.  He writes the equations shown to model the relationship between the number of pounds of peaches, p, and the number of pounds of grapefruit, g, that he buys.

​p + g = 2.5
1.58p + 1.09g = 3.46

What is the total number of pounds of peaches and grapefruit that Juan buys?

An equation is given.

5y - 2x = 5

​Create an ordered pair that represents​ one point on the graph of the equation.
