6 = 3x
2 = x
Answer: x = 2
Assuming the size of the whole remains constant, as you divide the whole into more pieces, each piece must be smaller. For example, when a whole is divided into four pieces vs nine pieces, 1/4 of the whole is larger than 1/9 of a whole.

Answer:
Each pipe is 24m
Step-by-step explanation:
<u>Given:</u>
- three pipes
- combined equal 72m
- let the variable x represent the length of 1 pipe
<u>Algebraic Expression</u>:
3 pipes times length equals 72m (the total length)
3x = 72, we want x to be alone so divided both sides by 3
3x / 3 = 72 / 3
x = 24
