Khan academy (8th grade math ) ,

k=37

Step-by-step explanation:

If we plug in 2 for t, which it tells us is the input, then the output of the problem will be 37

k=13t-2

Plug in the value for t.

k=13(2)-2

k=39-2

k=37

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

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.
