Consider some 4-sided dice. roll two of these dice. let x be the minimum of the two values that appear. let y denote the maximum. let a j be the event containing all outcomes in which the minimum of the two dice is j or greater. let x j indicate whether a j occurs. then x = x 1 + x 2 + x 3 + x 4 .

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

0.5?

hope your goes well, here's a turkey
