on a girls volleyball team 9 out of 12 team members have played in previous years based on this information if 80 girls are in a volleyball league than how many could be expected to have played the year before?​

I believe the answer is 60

Step-by-step explanation:

9/12 = 3/4

If we do cross multiplying x over 80 times 3/4 it equals 60.

I am sorry if it is not correct I'm not fully sure but I hope this helped!!

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
