9 ∙ 3 - 7 ∙ 9 2 + 4( 8 - 4)

-601

Step-by-step explanation:

So first you solve the equations in the parantheses.

8-4= 4 so its going to be

9x3-7x92+4(4)

You are going to multiply 4(4) and get 16

Now it's 9x3-7x92+16

You are going to multiply what needs to be multiplied now so:

9x3= 27 and 7x92=644

So it's:

27-644+16

It doesn't matter whether you do subtraction or addition first, whichever is the first equation so:

27-644= -617 then -617+16= -601

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.
