Hey!

-------------------------------------------------

Solution:

-5x + 15 = 35 - 10x

~Subtract 15 to both sides

-5x + 15 - 15 = 35 - 10x - 15

~Simplify

-5x = 20 - 10x

~Add 10x to both sides

-5x + 10x = 20 - 10x + 10x

~Simplify

5x = 20

~Divide 5 to both sides

5x/5 = 20/5

~Simplify

x = 4

-------------------------------------------------

Answer:

x = 4

Answer:

x = 4

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-5*x+15-(35-10*x)=0

Pull out like factors :

5x - 20 = 5 • (x - 4)

_________________________________________

Solve : 5 = 0

This equation has no solution.

A a non-zero constant never equals zero.

_________________________________________

Solve : x-4 = 0

Add 4 to both sides of the equation :

x = 4

hodyreva [135]

The most logical order is:
- The coordinates of point D and E by the midpoint formula.
- Slope of segment DE and slope of segment AC.
- Segment DE is parallel to segment AC. Slopes of parallel lines are equal.
- Length of segment DE and length of segment AC by the distance formula.
- Segment DE is half the length of segment AC by the substitution.

lbvjy [14]

Answer:

Depreciation expense year 1: $ 542.86
Book value at the end of year 1: 3,557.14

Explanation:

1) Depreciation = [purchase price - residual value] / [useful life]

2) Depreciation = [$ 4100 - $ 300] / [7 years] = $ 542.86 / year

That is the depreciation expense after year 1.

3) The book value will be the purchasing value less the depreciation accumulated, which is that of one year: $ 4100 - $ 542.86 = $ 3,557.14
