Answer:
290 adults and 190 children attended the Play.
Step-by-step explanation:
Given:
Total number of people in play = 480
Let the number of adults be x
and Number of children be y
Hence we can write the equation as;
Also Given:
Price for 1 adult = $2
Price for 1 children = $1
Total admission receipts = $770
Hence we can write the equation as;
Now We will subtract equation 1 from equation 2 we get;
Now substituting the value of x in equation 1 we get;
Hence 290 adults and 190 children attended the Play.
The problem is solved by creating two equations based on the given information and solving the system of equations to find that there were 290 adults and 190 children who attended the play.
To solve the problem of determining how many adults and children attended the play, we need to set up a system of equations.
Let A be the number of adults and C be the number of children who attended the play. We are given two pieces of information:
The total number of people at the play was 480, which gives us the equation A + C = 480.
The total amount of money collected from admissions was $770. Since adults pay $2 and children pay $1, the equation is 2A + C = 770.
Now we have a system of two equations:
A + C = 480
2A + C = 770
To solve this system, we can subtract the first equation from the second equation to eliminate C:
2A + C - (A + C) = 770 - 480
which simplifies to:
A = 290
Now, plug A = 290 into the first equation to find C:
290 + C = 480
Subtract 290 from both sides:
C = 190
So, there were 290 adults and 190 children at the play.

B) 120°
C) 90°
D) 180°
The sum of the measures of ∠3 and ∠4 is 180°.
To find the sum of the measures of ∠3 and ∠4, we need to know the relationship between these angles and ∠1 and ∠2. If the sum of the measures of ∠1 and ∠2 is 180°, this means that these two angles are supplementary. In other words, they add up to 180°. Since angles ∠3 and ∠4 are corresponding angles with ∠1 and ∠2, they will also be supplementary to each other. Therefore, the sum of the measures of ∠3 and ∠4 is 180° as well.
