Directions: follow the instructions for the following inequalities. 1.4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2.11 >-2 Add 3 to both sides, then add 3,
then add (-4)
3.-2 <-2 Subtract 6 from both sides, then 8, and then 2
4.-4 < 8 Divide both sides by-4, then by-2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true?
Why or why not?

the answers c

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
