Recall that the data from Poly and Digit’s survey is normally distributed with a mean of 5.9 and a standard deviation of 1.21. Lutwidge is Poly's pet dragon and is 10 feet tall. Charlemagne is Digit's pet dragon and is 4 feet tall. What is the z-score of each pet?

x/3-10=8

x/3=18

x=48

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
