Does a two-digit number exist such that the digits sum to 9 and when the digits are reversed the resulting number is 9 greater t
Alexeev081 [22]

The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

I hope this helps!

Neporo4naja [7]

Answer:

$75

Step-by-step explanation:

<h3>Steps to determining the answer</h3>
  1. Determine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week.
  2. Multiply the answer gotten from one above by the price of the ticket

20 - 14 = 6

6 students would pay in the second week

6 x $12.50 = $75

The teacher would collect $75 in the second week
