Answer: 40 adult tickets and 35 child tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of child tickets that were sold.
April sold 75 tickets to a school play. It means that
x + y = 75
If the adult tickets cost $8 each and child tickets cost $5 each and and a total of $495 was collected from ticket sales, it means that
8x + 5y = 495- - -- - - - - - - - -1
Substituting x = 75 - y into equation 1, it becomes
8(75 - y) + 5y = 495
600 - 8y + 5y = 495
- 8y + 5y = 495 - 600
- 3y = - 105
y = - 105/-3
y = 35
x = 75 - y = 75 - 35
x = 40
What is (75 x 2) + (6-3)
Answer:
(75x2)+(6-3)
These equations are in parentesis so they happen first.
75x2=150. If we take 70 and multiply it by 2 we get 140. If we multiply 5 by 2 we get 10. So 140+10=150.
6-3 is next. That is common knowledge and we know its 3.
No we add 150+3=153 to get our answer.
Parenthesis first
Exponets after parenthesis

I hope this helped and if so plz give brainliest.
Answer:
153
Step-by-step explanation:
(75 x 2) + (6-3)
150+(6-3)
150+3
153
the height of the previous bounce. Let n = bounce number. Before the ball is
dropped, n = 0, because the ball has not yet bounced. Which explicit formula
represents the height of the ball after n bounces?
The height of the ball after n bounces is given by the formula a_n = 12 * 0.75^(n - 1). This formula represents a geometric sequence where each height is 75% of the previous height.
The height the bouncy ball reaches after each bounce is a geometric sequence, where each subsequent height is found by multiplying the previous height by the common ratio, 75%, or 0.75. The initial term is the original height from which the ball is dropped, which is 12 meters.
The explicit formula for a geometric sequence is a_n = a_1 * r^(n - 1). Replacing a_1 with 12 (the initial height), r with 0.75 (the common ratio), and n with the bounce number, the explicit formula to find the height of the ball after n bounces is a_n = 12 * 0.75^(n - 1).

Answer:
Max. height following bounce # n is 12(¾)n because each prior height is multiplied by three fourths.
