9x/2<=6(x-3)+3x
solve using that method in picture!

help
please. ASAP

x 4

Step-by-step explanation:

9x/2 6(x - 3) + 3x

9x/2 6x - 18 + 3x

9x/2 9x - 18

mltiply both sides by 2

9x 18x - 36

subtract  18x from both sides

-9x -36

divide both sides by -9

flip the side when dividing by a negative

x 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
