Given: made = 60° and mcdf = (3x + 15)° prove: x = 15 what is the missing statement and the missing reason in step 5? statement: 60 = 3x + 15; reason: substitution statement: x = 15; reason: subtraction property of equality statement: 60 = 3x + 15; reason: transitive property statement: x = 15; reason: subtraction and division properties of equality

Statement: x =15.

Reason: Subtraction and Division properties of equality.

Explanation:

Given: and  

⇒  

⇒ 60= 3x+15 or

Subtraction property of equality: Subtract the same number from both sides of an equation.

Subtract 15 from both sides of an equation;

 or

45=3x

Division property of equality: Divide the same number from both sides of an equation;

Divide by 3 from both sides of an equation, we have

Simplify:

x=15        Hence proved!

The answer is:    A) Statement: 60 = 3x + 15; Reason: substitution
