If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

Value of X is  9 and  Angle 6 is  79°

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

Since, angle 1 and angle 4 are vertically opposite angles . Hence, these are equal.

∠1 = ∠4 = 11x + 2

Similarly, ∠6 and ∠7 are vertically opposite angles.

Thus,  ∠6 = ∠7 = 8x + 7

If two parallel lines are cut by a transversal, then the sum of interior angles on one side is equal to 180 degree.

Therefore,   ∠4 + ∠6 = 180

                 11x + 2 + 8x + 7 = 180

                  19x + 9 = 180

                  19x = 171

                   x = 9

Value of angle 6 = value of angle 7

                           = 8x + 7

                        = 8 (9) + 7

                        = 79 Degree

In August 2016, Richard purchased and placed in service an office building costing $753,000, including $134,000 for the land. Th
Schach [20]

Only the building is depreciable

so the depreciable portion is $753,000 less <span>$134,000  </span>land, for a net of $619,000

 The MACRS rules (Modified Accelerated Cost Recovery System ) provide a 39-year life, straight-line depreciation, and a "mid-month" acquisition convention that treats the property as acquired in the middle of the month, regardless of the actual date of acquisition.

 Therefore, the August 1, Year 2016, service date provides a half-month's depreciation for August, plus a full month for September through December, for a total of 4.5 months for Year 2016. $619,000 /39 years) × (4.5/12) = $5,952.

Pleaseeeee helppp!!!!
Lelechka [254]

Answer:

x + 6

Step-by-step explanation:

(f ÷ g)(x) = f(x) ÷ g(x), that is

\frac{x^2-3x-54}{x-9} ← factorise numerator

= \frac{(x-9)(x+6)}{x-9} ← cancel the common factor (x - 9), leaving

= x + 6

Four x plus two times two x minus one
Bad White [126]

Answer:

<h2>8x - 1</h2>

Step-by-step explanation:

Four x: 4x

Two x: 2x

Two times two x: 2(2x) = 4x

Four x plus two times two x minus one: 4x + 2(2x) - 1 = 4x + 4x - 1

<em>Combine like terms:</em> = (4x + 4x) - 1 = 8x - 1
