Answer: a child ticket costs $14.50
Step-by-step explanation:
x=children ticket
x+4.50=adult ticket
3 children and 2 adult
3x+2(x+4.50)=81.50
3x+2x+9.00=81.50
5x+9.00=81.50
5x+9.00-9.00=81.50-9.00
5x=72.50
5x/5=72.50/5
x=14.50
The value of y is 11 if the measure of the angle (x + 6y) is 90 degree and x = 24 option first is correct.
<h3>What is a perpendicular line?</h3>
Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other known as parallel lines.
We have a perpendicular line shown in the picture.
The measure of the angle (4x - 6) is equal to 90 degree.
4x - 6 = 90
4x = 96
x = 24
Similarly, the measure of the angle (x + 6y) is equal to 90 degree:
x + 6y = 90
Plug x = 24
24 + 6y = 90
y = 11
Thus, the value of y is 11 if the measure of the angle (x + 6y) is 90 degree and x = 24 option first is correct.

The answer is 48 units squared
We have to find the greatest common factor from the given expression. The greatest common factor is such a term which can be taken out common from each term of the expression leaving behind no common element between the terms of the expression.
If you observe the given polynomial, you will see that the greatest common factor is 7x. So the factorization of the polynomial will be:
So option A gives the correct answer to the question
