📝 Answered - Last month Maria hiked a total of 90 miles on two hiking trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail. Which equation can be used to find the number of times Maria hiked each trail? A. 50 - 10y = 5x B. 5x - 10y = 90 C. x + y = 90 D. 90 + 10y = 5x

📝 Answered - The table shows the gallons of fuel remaining after a car travels a certain distance in miles. \begin{tabular}{|c|c|} \hline \begin{tabular}{c} Distance \\ (miles) \end{tabular} & \begin{tabular}{c} Fuel Remaining \\ (gallons) \end{tabular} \\ \hline 0 & 13.50 \\ \hline 1 & 13.46 \\ \hline 2 & 13.42 \\ \hline 3 & 13.38 \\ \hline 4 & 13.34 \\ \hline 5 & 13.30 \\ \hline \end{tabular} The change in fuel remaining from one row to the next in the table is $\square$ -0.04 gallon(s). The change in distance from one row to the next in the table is $\square$ 1 mile(s). The slope of the line that runs through the points given in the table is $\square$ -0.04 . The slope indicates a $\square$ gain of 0.04 gallons of fuel for every 1 mile gain of 1 gallon of fuel for every 0.04 mile loss of 0.04 gallons of fuel for every 1 mile loss of 1 gallon of fuel for every 0.04 mile
