Does this table show a proportional relationship? If so, what is the constant of proportionality?

The answer is A: Yes 1/4 is the constant property.

This is because the x ration to y is 3 to 12. So we divide 12 by 3 to get our answer which is 4. That is equivalent to 1/4 since we divided.

I hope this helps and if it did pls give me brainliest!

Step-by-step explanation:

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
