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!!

answer: 40.95

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
