Bob lives 2.8 miles from Sue and 1.6 miles from Cue. Write a double inequality to represent the possible distances d between Sue's home and Cue's home.

0 <= x <= 4.4

Step-by-step explanation:

Let x be the distance between their homes.

using triangular inequality:

x <= (2.8 + 1.6) miles

0 <= x <= 4.4

Therefore, The double inequality to represent the possible distances d between Sue's home and Cue's home is 0 <= x <= 4.4

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
