Question

What is the missing reason for line 5 in this proof?


A. Addition property of =

B. Sub situation property of =

C. Division property of =


D. Division of real numbers

Answer 1

Line 5 shows the division property of equality. 

The division property of equality states that you can divide both sides of the equation by the same number and the equation remains the same. This equation is being divided by 4 on both sides.

Answer 2

Answer: C. division property of =

Explanation:

All you simply did was divide the terms on each side by 4.

So, 4x = 12 becomes (4÷4)x = 12÷4, which is what was done on line 5.

The division property is when both sides of an equation are divided by the same number.

Bonus:

Line 8- D. multiplication of real numbers

Line 3- B. substitution property of =

Line 2- D. segment addition postulate

I hope this helped!

Good luck <3
