The amount of time required to travel a certain distance is equal to quotient of distance and speed. We let x be the speed of Terry and Mark's will be x+2. The equation that would best represent the scenario is,
15/x = 21/(x+2)
The value of x is 5. Thus, Mark's speed is 7 mph.

(123+2"51=?=90.356821.2344
Answer:
-4X-10
Step-by-step explanation:
Weight of the dog in question = 44 pounds
Amount of weight the dog needs to reduce as per the veterinarian = 7 pounds
Let us assume the new weight of the dog in question = x
Then
44 - x = 7
This equation can also be represented as
x + 7 = 44.
So from the above deductions we can say that 44 - x = 7 is the correct equation. Another equation to represent the situation given in the question is x + 7 = 44
