The "double-r-7" ranch has a new owner. the 20 animals, all hummingbirds and mice, are dismayed, as they have heard that he is both foolish and inexperienced. not being quite sure what he was looking for, however, he checked on the health of his animals by inspecting all their feet. there were 64 feet in all. how many hummingbirds and how many mice are on this ranch?

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
