I think the first one might be 18 second might be 10
Answer:
D
Step-by-step explanation:
8 is LESS THAN 1/2x
so youd take those numbers and multiply by 1/2
C, B, and A are all under 8, so that would be wrong
when you multiply 1/2 with 17, you get 8.5 which is bigger than 8. then everything else above that is more than 8, therefore D is the right answer.
468 seats is the answer.
26 x 18
or
13 x 2 x 9 x 2
both equal 468
