Answer: 96 adult tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of students tickets that were sold.
For the last basketball game, 381 tickets were sold. This means that
x + y = 381
Adult tickets sold for $7, and student tickets sold for $3. If the ticket sales totaled 1,527, it means that
7x + 3y = 1527 - - - - - - - - - - - -1
Substituting x = 381 - y into equation 1, it becomes
7(381 - y) + 3y = 1527
2667 - 7y + 3y = 1527
- 7y + 3y = 1527 - 2667
- 4y = - 1140
y = - 1140/- 4
y = 285
x = 381 - y = 381 - 285
x = 96
Answer:
x = 12

Step-by-step explanation:
Let the ages of son and daughter be 5x and 4x Then
By the question
The age of a man is equal to the sum of the ages of his son and daughter . So
5x + 4x = 9x
Now
it is given that
age of the man = 45
or 9x = 45
x = 45 / 9
x = 5
Finally
Age of son = 5x = 5 * 5 = 25
Age of daughter = 4x = 4 * 5 = 20
Hope it will help :)❤
