The word 'difference' indicates the use of subtraction in a Mathematical sum

The error is that the sum could be 15 - 5y instead of 5y - 15

A subtraction sum does not have the commutative properties, meaning that we cannot do the sum in any order. 

A sum 15 - 5y will give a different result with the sum 5y - 15 for the same value of y.

What is the absolute value of 1.7​
vodomira [7]

Answer:

<h2>|1.7| = 1.7</h2>

Step-by-step explanation:

Definition of absolute value:

|a| = a if a ≥ 0

|a| = -a if a < 0

Examples:

|2| = 2

|-2| = -(-2) = 2

|0.45| = 0.45

|-0.45| = -(-0.45) = 0.45

|1000| = 1000

|-1000| = 1000

Therefore

|1.7| = 1.7
