1200x + 360(x - 10) = 33,840
1200x + 360x - 3600 = 33,840
1560x - 3600 = 33,840
1560x = 33,840 + 3,600
1560x = 37,440
x = 37,440 / 1560
x = 24..... main level seats cost $ 24 <==
balcony seats cost (24 - 10) = $ 14 <==
Answer:
WX=ZY would prove that the quadrilateral WXYZ is a parallelogram
Step-by-step explanation:
it is 2(x-4)+3x=22 2(6-4)+3(6)
You have to add the areas of the three rectangles.
A1 = 39*11 = 429 m²
A2 = (39-12)*7 = 27*7 = 189 m²
A3 = 10*6 = 60 m²
A = 429 + 189 + 60 = 678 m².
Hope this helps !

Answer: a. 7
Step-by-step explanation: <u>Degrees</u> <u>of</u> <u>Freedom</u> is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7
