Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to call the numbers x and y.
A number is equal to twice a smaller number plus 3.
Greater number is x, and smaller is y. So
The same number is equal to twice the sum of the smaller number and 1.
This means that
Equaling the values for x:
Since division by 0 does not exist, it means that there is no solution for the system.
We have 11 as our base value, meaning that we add 11 to something, so we have 11+<something>. To find that something, we want to know how long it takes to go 21.78 miles at 33 miles per hour. To get this, we want to turn miles per hour into minutes per mile and multiply that by 21.78 miles to get our answer. Therefore, we cross them out as shown in the equation to get
