Will give highest ! 36 points to correct answer cindy has 26 nickels. she is getting rolls of nickels from the bank. she has enough money to get up to 10 rolls of nickels and each roll contains 40 nickels. the bank will not give partial rolls. the function that models the number of nickels cindy will have after leaving the bank is f(r)=40r+26, where r is the number of rolls of nickels she gets. what is the practical domain of the function?

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

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 represent 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? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
