What is the value of x? 20 35 60 70

They are vertical angles, and so set them equal to each other

x + 40 = 3x

Isolate the x. Subtract x from both sides

x (-x) + 40 = 3x (-x)

Simplify

40 = 3x - x

40 = 2x

Isolate the x. Divide 2 from both sides

40/2 = 2x/2

x = 40/2

x = 20

20, or (A) is your answer

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
