Write and solve an equation. If 14 empty water bottles weigh 4.5 pounds, what will 9 empty water bottles weigh?

Solution:

Given that,

14 empty water bottles weigh 4.5 pounds

Weight of 9 empty bottles = 9 x weight of 1 empty bottle

Weight of 9 empty bottles = 9 x 0.3214

Weight of 9 empty bottles = 2.8926

Thus weight of 9 empty water bottles is 2.8926 pounds

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|
