Solve 2x + 8< 10 or 2x + 8 > 20

x<1

x>6

Step-by-step explanation:

solve 2x+8<10:

2x+8<10

2x<2

x<1

solve 2x+8>20:

2x+8>20

2x>12

x>6

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
