Answer:
250
Step-by-step explanation:
Let 'a' represent the number of adult tickets.
a +(a -73) = 427
2a = 500 . . . . . add 73
a = 250 . . . . . . divide by 2
250 adult tickets were sold.

<em>Additional comment</em>
I call this a "sum and difference problem" because we are given the total of two values and the difference between them. As you can see here, the larger of the two values is the average of the given numbers, their sum divided by 2. This is the generic solution to such a problem: the larger number is the average of the given sum and difference.
Answer:
do 3 divided by 10 to get the decimal
Step-by-step explanation:
C would be the answer as

is the same thing as x * x * x * x.

The given figure is a cylinder.

Take the derivatives of each to get the tangent vectors:


Take the cross product of the tangent vectors to get a vector that is normal to both lines:

The two given lines intersect when
:

that is, at the point (6, 4, 4).
The line perpendicular to both of the given lines through the origin is obtained by scaling the normal vector found earlier by
; translate this line by adding the vector
to get the line we want,
