Answer:
320 Student Tickets
180 Adult Tickets
Step-by-step explanation:
You can solve this problem by using system of equations. First, we need to figure out our equations.
Equation 1: x as students and y as adults
![x+y=500](https://tex.z-dn.net/?f=x%2By%3D500)
We get this equation because the total tickets sold was 500. The x represents the students sold to students, and the y represents the tickets sold to adults.
Equation 2:
![3x+5y=1850](https://tex.z-dn.net/?f=3x%2B5y%3D1850)
We get this equation based on the prices. Each student ticket costs $3, and each adult ticket costs $5. The total amount earned was $1850.
Now that we have out equations, we can use system of equations to find our students and adults.
![x+y=500](https://tex.z-dn.net/?f=x%2By%3D500)
![3x+5y=1860](https://tex.z-dn.net/?f=3x%2B5y%3D1860)
Typically elimination is the easiest strategy because you are able to cross out variables.
![3(x+y=500)](https://tex.z-dn.net/?f=3%28x%2By%3D500%29)
![3x+5y=1860](https://tex.z-dn.net/?f=3x%2B5y%3D1860)
Becomes:
![3x+3y=1500](https://tex.z-dn.net/?f=3x%2B3y%3D1500)
![3x+5y=1860](https://tex.z-dn.net/?f=3x%2B5y%3D1860)
We see that both equations now have 3x. We can cancel out 3x.
![-2y=-360](https://tex.z-dn.net/?f=-2y%3D-360)
![y=180](https://tex.z-dn.net/?f=y%3D180)
Now that we know y=180, we can plug it back into one of our equations to find x.
![x+180=500](https://tex.z-dn.net/?f=x%2B180%3D500)
![x=320](https://tex.z-dn.net/?f=x%3D320)
320 student tickets and 180 adult tickets were sold.
Answer:
156 degrees
Step-by-step explanation:
The four angles in any quadrilateral add to 360 degrees. Add the given degrees and subtract that number from 360 for your answer
Answer:
d. 4x+1
Step-by-step explanation:
(5x+3)-(x+2)
5x-x=4x
3-2=1
Final answer= 4x+1
282 because if u multipy 94 into 3 u get 282 and to check 282 divided by 3 is 94
Answer:
0.34
Step-by-step explanation:
The total probability is equal to one.
P (Dr. Green) = 1 - (0.25 + 0.17 + 0.21 + 0.03)
= 1 - 0.66
= 0.34
