the second step is divide both sides by 3
the answer is x=8
Step-by-step explanation:
Area of Parallelogram ABCD is equivalent to the area of rectangle AXBY.
Area of rectangle AXBY= Length AX * Length AB= 3 ft * 4√2 ft = 12√2 sq.ft.
Thus Area of Parallelogram is 12√2 sq.ft.
Answer:
15 early tickets were sold and 5 regular tickets were sold.
Step-by-step explanation:
Let x be the number of early bird tickets sold and y be the number of regular tickets sold.
Total number of tickets sold = 20
Thus, we can write the equation,
![x + y = 20](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2020)
Cost of early bird ticket = $10
Cost of regular tickets = $15
Total cost = $225
Thus, we can write the equation,
![225 = 10x + 15y](https://tex.z-dn.net/?f=225%20%3D%2010x%20%2B%2015y)
We solve the equation by elimination method by multiplying first equation by 10 and subtracting.
![10x + 15y-(10x+10y) = 225 - 200\\5y = 25\\\Rightarrow y=5\\x + 5 = 20\\\Rightarrow x = 15](https://tex.z-dn.net/?f=10x%20%2B%2015y-%2810x%2B10y%29%20%3D%20225%20-%20200%5C%5C5y%20%3D%2025%5C%5C%5CRightarrow%20y%3D5%5C%5Cx%20%2B%205%20%3D%2020%5C%5C%5CRightarrow%20x%20%3D%2015)
Thus, 15 early tickets were sold and 5 regular tickets were sold.
