How many solution does this linear system have 2x-y=7 y=2x+3

NO SOLUTION

Step-by-step explanation:

We can make this problem easier to understand if we write the system vertically:

2x-y=7

y=2x+3

and then rewrite the first problem in the form y = mx + b:

2x-y=7   ↔    y + 7 = 2x   ↔  y = 2x + 7

y=2x+3

Note how these two equations have the same slope, but different y-intercepts.  This tells us that the two lines are parallel, which in turn tells us that they never intercept one another.

Thus, this system has NO SOLUTION.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
