Question

Use the indicated properties of realnumbers to complete the blanks of the following statements.

SOMEBODY PLEASE HELP URGENT!!!​

Answer 1

13.
`50+43=43+50`

14.
`5+(7+6)=(5+7)+6`

15.
`-15+0=0-15=-15`

16.
`(3)/(4)*(4)/(3)=1`

17.
`25*4=4*25`

Explanation:

Let "a", "b", and "c" real numbers.

- Commutative Property of Addition states that:

`a+b=b+a`

- Associative Property of Addition states that:

`(a+b)+c=a+(b+c)`

- Additive Identity Property states that:

`a+0=0+a=a`

- Commutative Property of Multiplication states that:

`a*b=b*a`

- Multiplicative Inverse Property states that:

`a*(1)/(a)=1` (
`a\\eq 0`)

Knowing these properties, we can solve the exercise:

13. By the Commutative Property of Addition:

`50+43=43+50`

14. By the Associative Property of Addition:

`5+(7+6)=(5+7)+6`

15. By the Additive Identity Property:

`-15+0=0-15=-15`

16. By the Multiplicative Inverse Property:

`(3)/(4)*(4)/(3)=1`

17. By the Commutative Property of Multiplication:

`25*4=4*25`
