Answer:

2(4 + 2z) = 8 + 4z

or

2(4 + 2z) = 0

z = -2

Step-by-step explanation:

How to solve:

2(4 + 2z)

Distribute:

2(4 + 2z)

2(4) + 2(2z)

Multiply:

2(4) + 2(2z)

8 + 4z

8 + 4z is the simplified expression.

How to solve:

2(4 + 2z) = 0

Distribute:

2(4 + 2z) = 0

2(4) + 2(2z) = 0

Multiply:

2(4) + 2(2z) = 0

8 + 4z = 0

Subtract 8 on both sides:

8 + 4z = 0

-8          -8

4z = -8

Divide by 4 on both sides:

4z = -8

/4      /4

z = -2

z = -2 is the answer if 0 is on the other side of the equal sign

Farmer Company purchased equipment on January 1, Year 1 for $82,000. The equipment is estimated to have a 5-year life and a salv
aalyn [17]

Answer:

option (a) $6,240

Step-by-step explanation:

Given:

Purchasing cost of the equipment = $82,000

Estimated life = 5 years

Salvage value = $4,000

Revised expected life = 8 years

Now,

Depreciation per year = \frac{\textup{82,000-4,000}}{\textup{5}}

therefore,

The accumulated Depreciation at the beginning of year 4

= Annual depreciation × years passed

= 15,600 × 3

= $46,800

Thus,

The book value at the beginning of year 4

= Purchasing cost - Depreciation

= $82,000 - $46,800

= $35,200

Now,

The remaining life = Revised estimated life - Years passed

= 8 - 3

= 5 years

therefore,

Depreciation expense =\frac{\textup{book value at the beginning of year 4 - salvage value}}{\textup{Revised estimated life}}

= \frac{\textup{35,200  - 4000}}{\textup{5}}

= $6,240

Hence,

The correct answer is option (a) $6,240

So, all you have to do is multiply 6 and 2.

In \frac{1}{2} If you add \frac{1}{2}+\frac{1}{2} it equals 1 whole.

If 2 \frac{1}{2} equals 1 whole. You multiply 6 by 2.

Hope this helped!
