Answer:
250
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 53= the number of student tickets sold
x + x + 53 = 553
2x = 500
x = 250
2x + 53 = 553
Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47
