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
D must be perpendicular to a because d is parallel to c. c is perpendicular to b. b is parallel to a.

I believe it's reflexive property because reflexive property is when a=a or 6=6 or 5=5 and abc=abc
