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) Responses 2d=570 2 d is equal to 570 d+255=570 d plus 255 is equal to 570 d−255=570 d minus 255 is equal to 570 d−570=255
Elaborate
The equation that could be used to solve this problem is (2d = 570). This equation represents the combined distance traveled by Mark and David, where d represents the distance David traveled. By substituting the given value of Mark's distance (255 miles), the equation can be solved to find the distance David traveled.
The equation that could be used to solve this problem is "d + 255 = 570". In this equation, "d" represents the distance David traveled.
To solve this problem, we can use the equation "2d = 570", where d represents the distance David traveled.
This equation is derived from the fact that together Mark and David traveled 570 miles. Since Mark traveled 255 miles, we can assume that David traveled some distance, represented by d.
Adding Mark's distance (255) to David's distance (d) should give us the total distance of the trip (570 miles). Therefore, the equation to solve this problem becomes "d + 255 = 570".
Alternatively, we could subtract Mark's distance (255) from the total distance (570 miles) to find David's distance. In this case, the equation would be "570 - 255 = d" or simplified as "315 = d".
So, choosing the equation "d + 255 = 570" would help us find the distance traveled by David.
