I don't understand how to solve this

i think you need to solve the formula from the inside the parenthesis first then you would have to find the absolute value.

Step-by-step explanation:

y = x + 95

y = 42 + 95

y=137 mm hg

a

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|
