Question

Select all that justify the following statement. 8x1/8+(-1)+5=5

commutative - addition
inverse - addition
associative - multiplication
symmetric
commutative - multiplication
associative - addition
inverse - multiplication

Answer 1

1) inverse multiplication

2) Cumulative addition

3) Inverse addition

Explanation:

While solving the expression we will mention the statements.

`8* (1)/(8)+(-1)+5 = 5`

We will solve the left hand side of the given equation to get the right side.

`8* (1)/(8)= [tex](8)/(8) =1` (inverse multiplication)

Now expression becomes

`1+(-1)+5`

in this expression 1 + 5 = 6 ( cumulative addition)

Now the expression is

6 +(-1 ) = 5 (inverse addition)

So three statements are justifying the solution.

1) inverse multiplication

2) Cumulative addition

3) Inverse addition
