Step-by-step explanation:

because you would add -27 to -13 which would be -40

C, y with > and line 14

Step-by-step explanation:

Simple algrebra, with one single rule. When you divide or multiply the inequality flips side. So if you need to divide by 27, it would go from > to <. Just saying, in this case you don't need to. You are adding 27 to the other side, so -13 plus 27 is 14. No need to flip the inequality sign (>) so thats it. 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
