How is 20/100 = 13...
Anyways, look at the two fractions.
20/100 and 80/100
Notice how 20 times 4 equals 80?
So maybe, 13 * 4 = 52.
Answer:
a and 32
Step-by-step explanation:
Answer: 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Let be "o" the number of orchestra seats they bought and "m" the number of mezzanine seats they bought.
Set up a system of equations:
![\left \{ {{42o+25m=486} \atop {o+m=14}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B42o%2B25m%3D486%7D%20%5Catop%20%7Bo%2Bm%3D14%7D%7D%20%5Cright.)
You can apply the Substittution Method to solve the system of equations:
1. Solve for "o" from the second equation:
![o=14-m](https://tex.z-dn.net/?f=o%3D14-m)
2. Substitute it into the first equation and solve for "m":
![42(14-m)+25m=486\\\\588-42m+25m=486\\\\-17m=-102\\\\m=\frac{-102}{-17}\\\\m=6](https://tex.z-dn.net/?f=42%2814-m%29%2B25m%3D486%5C%5C%5C%5C588-42m%2B25m%3D486%5C%5C%5C%5C-17m%3D-102%5C%5C%5C%5Cm%3D%5Cfrac%7B-102%7D%7B-17%7D%5C%5C%5C%5Cm%3D6)
3. Substitute the value of "m" into
and evaluate, in order to find the value of "o". This is:
![o=14-6\\\\o=8](https://tex.z-dn.net/?f=o%3D14-6%5C%5C%5C%5Co%3D8)
I am pretty sure it's the second sentence.
12(x+2)(x-2) !!! have a great day
