Type the correct answer in each box. Use numerals instead of words. Consider the systems of equations below.
System A
System B
System C
12 + y2 = 17
= -5
y = 12 - 71 + 10
y = -63 + 5
y = -2:2 + 9
85 - y =-17
y =

the 3rd option is right

step-by-step explanation:

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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.
