Answer:

36

Step-by-step explanation:

Width = x

Length = 4x

Perimeter = Width + Width + Length + Length (Because there are four sides; two sides are the widgth and two sides are the length)

30 (because 30 is given as the perimeter) = x + x + 4x + 4x

30 = 10x

x = 3

Width = 3

Length = 4(3) = 12

Area = Width * Length

Area = 3 * 12 = 36

A building worth $829,000 is depreciated for tax purposes by its owner using the straight-line depreciation method.
Delvig [45]

The value of the building would be $699,400 in 4 years.

<h3>What will be the value of the building?</h3>

Depreciation is the when the value of an asset reduces as a result of wear and tear. Straight line depreciation is a method used in depreciating the value of an asset linearly with the passage of time.

The equation that can be used to determine the value of the building with a straight line depreciation is:

Value of the asset = initial value of the asset - (number of months x deprecation rate)

y = 829,000 - 2700x

The first step is to determine the number of months it would take for the building to have a value of $699,400.

$699,400 =  829,000 - 2700x

829,000 - 699,400 = 2,700x

129,600 = 2,700x

x = 129,600 / 2,700

x = 48 months

Now convert, months to years

1 year = 12 months

48 / 12 = 4 years

Answer:

Step-by-step explanation:

3C + 8T = 58 ----- (eq1)

5C + 2T = 23 ------(eq2)

Multiply equation (1) by 5 and equation (2) by 3

15C + 40T = 290 -----(eq3)

15C + 6T = 69 ----------(eq4)

Subtract equation (4) from (3)

34T = 221

T = 221/34

T = $6.5

Therefore 1 Table will cost $6 and 5 cents

Solve for (C) in equation (1)

3C + 8T = 58

3C + 8(6.5) = 58

3C + 52 = 58

3C = 58-52

3C = 6

C = 6/3

C = $2

1 Chair will cost $2
