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:
You can apply the Substittution Method to solve the system of equations:
1. Solve for "o" from the second equation:
2. Substitute it into the first equation and solve for "m":
3. Substitute the value of "m" into and evaluate, in order to find the value of "o". This is:
Answer:
BE= 19
Step-by-step explanation:
4x+3 = 12x-10
2(4x+3) = 12x-10
8x+6 = 12x-10
8x-8x+6 = 12x-8x-10
6 = 4x-10
10+6 = 4x-10+10
16 = 4x
16/4 = 4x/4
4 = x
BE 8(4)+6 = 38 38/2 = 19
AC 12(4)-10 = 38
The diagonals of a rectangle are equal.
3 ÷ 2 = 1.5
So each student had a pack and a half.
Hope this helps. :)
