<h3>
Answer: 29</h3>
====================================================
Work Shown:
The two angles shown are a linear pair. They are adjacent and supplementary. Supplementary angles add to 180 degrees.
(4x-5)+(x+40) = 180
5x+35 = 180
5x = 180-35
5x = 145
x = 145/5
x = 29
--------
As a check, if x = 29, then
4x-5 = 4*29-5 = 116-5 = 111
x+40 = 29+40 = 69
The two angles are 69 and 111 degrees which add to 69+111 = 180, which helps confirm the answer.
Answer: He has earned $200 interest and the balance of his account is $1,200.
Step-by-step explanation:
Given: Principal : P = $1,000
Simple interest rate : r = 5% = 0.05
Time: t = 4 years
Simple interest = 
i.e. Simple interest = $200
Balance of account = Principal + Simple interest
= $1,000 + $200
= $1,200
Hence, he has earned $200 interest and the balance of his account is $1,200.
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
