What’s the distance 3 1/4 and -15

18 1/4

Step-by-step explanation:

The easiest way to do this is to start at 0 and go 3 1/4 units to your right.

Then start at 0 and go -15 units to your left.  So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.

The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.

A formula would look like this

distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )

distance = sqrt( (3 1/4 -  - 15)^2 + (4 - 4)^2 )

distance = sqrt(  (18 1/4 )^2 + 0)

distance = 18 1/4

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.
