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

Step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
