Cose is building a new fence in his garden. He uses 25 planks of wood, each of which is 30 cm long. He arranges these planks so that each pair of two adjacent planks overlaps by the same amount as shown below. The total length of Costa's new fence is 69 meters. What is the length of the overlap within each pair of adjacent planks, in centimeters?

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the anwser is d) 75°

step-by-step explanation:

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|
