The area is 49 hopefully this is right have a nice day
One ways is to find the factors of 36
1,36
2,18
3,12
4,9
6,6
add them
1+36=37
2+18=20
3+12=15 correct
4+9=13
6+6=12
the numbers are 3 nd 12
X= number of student tickets
Y= number of on student tickets
x+y=311
0.50x + 1.50y = 385.50
Solve x in 1st equation
X+y=311
X= -y + 311
Now substitute x into second equation to solve for y
0.50(-y+311)+ 1.50y = 385.50
-0.50y+311.50+1.50y=385.50
Y+311.50=385.50
Y= 385.50-311.50
Y= 74
Now substitute y answer to first equation to find x
X+y=311
X+ 74=311
X= 311-74
X= 237
So 237 students tickets and 74 non students tickets
By unit rate they mean feet per second
To do this you need to divide feet by seconds
692.08/21.1=32.8
The unit rate is:
32.8 feet per second
