Answer:

First step is "Solve the parenthesis". It means subtract 1.5x from 4x.

Step-by-step explanation:

The given equation is

$5(4x-1.5x)+12=4x-2$

We need to find the first step o solve this equation.

Step 1: Solve the parenthesis.

$5(2.5x)+12=4x-2$

Step 2: Multiply.

$12.5x+12=4x-2$

Step 3: Isolate variable terms on left side.

$12.5x-4x=-12-2$

$8.5x=-14$

Step 4. Divide both sides by 8.5.

$x=\dfrac{-14}{8.5}$

$x\approx -1.647$

Therefore, the firs step is "Solve the parenthesis".

If equipment cost $20,000 and accumulated depreciation amounts to $6,000, the book value of the equipment is?

Rina8888 [55]

The book value of the equipment is $14000

Given,

equipment cost = $20,000

depreciation amounts = $6,000

book value of the equipment = equipment cost - depreciation cost

= 20000 - 6000

= $14000

<h3>What Are Depreciation Expenses?</h3>

Depreciation expense, on the other hand, is the amortized portion of the cost of the business's fixed assets during a certain period. Depreciation expense is recognized in the income statement as a non-cash expense that reduces the net income or profit of the business. For accounting purposes, depreciation expense is debited and accumulated depreciation is credited.

Depreciation expenses are treated as non-cash expenses because periodic monthly amortization is not involved in cash transactions.

Answer:

The answer is x = 5.

Step-by-step explanation:

Given:

Δ ABC is an Isosceles triangle with AB = CA

m∠ ABC = ( 6x + 4 )°

m∠ BAC = 73°

m∠ BCA = ( 8y - 7 )°

To Find:

x = ?

Solution:

Properties of an Isosceles Triangle.

Base angles or two angles are equal.
Any two sides are equal.

Here , Δ ABC is an Isosceles triangle with AB = CA

∴ m∠ BAC = m∠ BCA

$73= 8y-7\\8y=73+7\\8y=80\\y=\frac{80}{10} \\y=10$

∴ m∠ BCA = ( 8y - 7 )°

= 8 × 10 - 7

m∠ BCA = 73 Which is same as ∠ CAB

Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.

$\angle ACB + \angle CAB + \angle CBA = 180$

Substituting the values we get,

$73 + 73 + (6x+4) = 180\\6x+4=180-146\\6x=34-4\\6x=30\\x=\frac{30}{6} \\x=5\\$

The answer is x = 5.
