The temperature change in a chemistry experiment was -2C every 30 min. The initial temperature was +6C. What was the temperature after 4 h

4 hours = 8 half hours

0, 1, 2, 3, 4, 5, 6, 7, 8 half hours

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|
