Answer:
[tex]D=2d-3[/tex]
Step-by-step explanation:
Let 'D' be the distance between Cleveland and St. Louis.
Given:
'd' is the distance between St. Louis and Chicago.
The distance between Cleveland and St. Louis is 3 miles less than 2 times the distance between St. Louis and Chicago. This means,
The distance 'D' is 3 miles less than 2 times the distance 'd'.
Now, framing in equation form we get:
2 times 'd' means multiplying 2 to 'd'. This gives [tex]2d[/tex]
Now, 3 miles less than [tex]2d[/tex] means subtracting 3 from [tex]2d[/tex]. This gives,
[tex]D=2d-3[/tex]
Therefore, the distance between Cleveland and St. Louis is given as:
[tex]D=2d-3[/tex]
