Choose the equation that could be used to solve this problem.
Together, Mark and David traveled 570 miles to the beach. If Mark traveled 255 miles, how far did David travel?
(1 point)
2d=570
d−255=570
d−570=255
d + 255 = 570
The equation that could be used to solve this problem is:
2d = 570
Where d represents the distance that David traveled.
The equation that could be used to solve this problem is "d - 255 = 570".
To understand why, let's break down the problem and the equation:
The problem states that Mark and David traveled a total of 570 miles together, with Mark traveling 255 miles. We need to find out how far David traveled.
Let's assume that the distance David traveled is represented by the variable 'd'. It's important to note that 'd' represents the distance traveled by David.
The equation "d - 255 = 570" is derived by subtracting the distance Mark traveled (255 miles) from the total distance traveled by both Mark and David (570 miles). This equation allows us to isolate the variable 'd' and solve for it.
By rearranging the equation, we can find the value of 'd':
d - 255 = 570
Adding 255 to both sides:
d = 570 + 255
d = 825
Therefore, David traveled 825 miles.
