Can someone please help me understand this

It's the last one.

Step-by-step explanation:

(6,30) → (x,y)

To find the answer, you "slide" to the right to 6. Then you go up to 30.

y → up (positive) and down (negative)

x → left (negative) and right (positive)

I hope this helps

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
