Question

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

Answer 1

Answer:

13. $50+43=43+50$

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

15.  $-15+0=0-15=-15$

16.  $\frac{3}{4}*\frac{4}{3}=1$

17. $25*4=4*25$

Step-by-step 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:

$a*\frac{1}{a}=1$    ($a\neq 0$)

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:

$\frac{3}{4}*\frac{4}{3}=1$

17. By the Commutative Property of Multiplication:

$25*4=4*25$
