Last month Maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. Let x re
present the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. If she hiked a total of 90 miles, which equation can be used to find the number of times Maria hiked each trail?
Number of times she climbed 5-mile mountain trail = x Number of times she climbed 10-mile trail = y total distance of the 5-mile mountain trail will be = 5*x =5x total distance of the 10-mile mountain trail will be = 10*y = 10y equation that can be used to find the number of times she hiked each trail is therefore 5x + 10y = 90
the expression is 3(15+7). An word problem could be there are 15 apples and 7 bananas. Someone needs to buy 3 times the amount of those. This is represented by that expression.
