Which one of the following compound inequalities has no solution?
O 8x + 15 < 4x - 5 and - 7x + 2 < - 6x + 3
O 2(x - 6) < – 3(x + 6) and 6(x + 3) > 9(x - 1)
0 – 5x – 1 > - 7x + 9 and - 4x – 7 < 5x + 11
2x + 3 < 3x – 4 and 3x + 7 > 5x – 9

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

1. minimum

2. 6400

3. eight

hope this !
