Determine the missing number for this sequence.

24.5

Step-by-step explanation:

To help find the missing number subtract 19 and 13.5=5.5

Then subtract 5.5 from 30,

30-5.5=24.5

You can test this by subtracting 5.5 from every known number and you should get

30-5.5=24.5,

24.5-5.5=19,

19-5.5=13.5, and so on.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
