P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
Step-by-step explanation:
It makes 2x^2-20-206=0
Find D
Then find X1 and X2
It can't be written in any lower term since they do not share a common factor
Positive, negative, or opposites
The number is 58 because its less than 60 and greater than 50 and 5+8 =13.
Hope this helped you!
