Find the value of n that makes DEF-XYZ when
DE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1, and

The value of is n=3

Given that,

Calculation is as follows:

5/4(4n+4)=7n-1.

Now distribute:

5n+5=7n-1.

Now simplify:

6=2n.

n=3

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.
