Does the value of x make the equation to 0. Why?
natka813 [3]

Answer:

Since there is no value of x that will ever make this a true statement, the solution to the equation above is “no solution”. Be careful that you do not confuse the solution x = 0 with “no solution”. The solution x = 0 means that the value 0 satisfies the equation, so there is a solution.

A train travels 58 kilometers in 4 hours, and then 80 kilometers in 4 hours. What is its average speed?
Olegator [25]
Average speed  = 

                 (total distance covered) / (time to cover the distance).

Total distance covered = (58km + 80km) =  138 km

Time to cover the distance = (4hr + 4hr) =  8 hours

Average speed  =  138km / 8hr  =  17.25 km/hour .

(That's less than 11 mph.  You could bike there faster!)
