2 answers:
<u>The interpreter attended </u><u>22 parent-teacher conference</u><u> and </u><u>5 school related assembly</u>
To solve this problem, we would write out two set of linear equations.
The data given on this problem are
- parent-teacher conference = $35.50
- school related assembly = $42
- The total number of engagements = 27
Let x represent the number of parent-teacher conference
let y represent the number of school related conference
<h3>Equations</h3><h3>From equation (i)
Put equation(iii) into equation (ii)
Put y = 5 into equation 1
From the above calculations, he attended 22 parent-teacher conference and 5 school related assembly.

Answer:
The number of seat when n is odd
The number of seat when n is even
Step-by-step explanation:
Given that, each successive row contains two fewer seats than the preceding row.
Formula:
The sum n terms of an A.P series is
a = first term of the series.
d= common difference.
n= number of term
l= last term
term of a A.P series is
n is odd:
n,n-2,n-4,........,5,3,1
Or we can write 1,3,5,.....,n-4,n-2,n
Here a= 1 and d = second term- first term = 3-1=2
Let of the series is n.
Here , n=t, a=1 and d=2
⇒(t-1)2=n-1
Last term l= n,, the number of term , First term = 1
Total number of seat
n is even:
n,n-2,n-4,.......,4,2
Or we can write
2,4,.......,n-4,n-2,n
Here a= 2 and d = second term- first term = 4-2=2
Let of the series is n.
Here , n=t, a=2 and d=2
⇒(t-1)2=n-2
Last term l= n, the number of term , First term = 2
Total number of seat
