Answer:
They bought 23 tickets for children and 52 for adults.
Step-by-step explanation:
So first you must find what i represents so here it is
A= Adult
C= Children
They both sold the tickets which is going to be
A + C = 75
Now here it shows
12= each adult ticket
8= each children ticket
find the equation like this 12 A + 8C = 808
Now to find the C
You can find by resolving it like this
C= 75 - A
Solve the A and C
4A = 208
A = 52
12 (52) + 8C = 808
624 + 8C = 808
Children = 23
Adult= 52
Step-by-step explanation:
43. P, U
44. 7
53. Airplanes can be traveling on different planes, one plane above the other. Cars on the same intersection are on the same plane.

a. You can choose (4 * 3 * 2)/(3 * 2) = 4 groups of 3 points in which order does not matter.
One of those combinations does not have K, so 3 combinations of the 4 have K.
p = 3/4
b. p = 1 since any three points are always coplanar.

Discussion:
The area of a square is (length of a side)^2. In this case,
Area = 9^2 = 81

Answer:
sin s = 36 / 42 = 18 / 21 = 6/ 7
sin R = 14 / 42 = 7 / 21 = 1 / 3
cos s = 14 / 42 = 1 / 3
cos R = 36 / 42 = 6 / 7
