5/9 (fraction simplified)
The expression 3P2 can also be read as "permutation of 3 taken 2". This represents the number of ways in which the 3 items are arranged with the emphasis on the arrangement of the first two other items.
Answer:
Number of Adults Ticket=393
Number Of Students Tickets=792
Step-by-step explanation:
Let 'x' be the Adult's tickets
Let 'y' be the Student's tickets
x+y=1185 (total sold tickets)
5x+y=2757(total cost of tickets)
-(5x+y=2757)x+y=1185
(-5x-y)- x+y=1185-2757
=-4x+0 = (-1572)
=-4x=(-1572)
x= (-1572)÷-4
=393
=x+y=1185
=393+y=1185
=y=792
So Number of Adults Ticket=393
Number Of Students Tickets=792

Answer:
4.17%
Step-by-step explanation:
Rate = interest earned / (principal x time)
70 / (4 x 420) = = 0.0417 = 4.17%
We are given the equations 3x+5y=-3 and x-5y=-5.
Both equations have a 5y term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.
3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8
The y terms cancel out since one is positive and one is negative. Now we can solve for x.
4x = -8

x = -2
Now plug -2 in for x in one of the original equations to find y.
(-2) - 5y = -5
-5y = -3
y = 3/5
Our answer as an ordered pair is (2, 3/5)
