Lo is leaving from work today at 5: 45 p. m. she has errands to run before she meets her friends for dinner at 8 p. m. if it takes lo 3/4 of an hour to run each errand, how many errands does she have time to run between work and dinner? 3/4x = 2 1/4 a. 5 b. 1 c. 3 d. 2

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
