<h2>The required value of x is equal to 2.</h2>
Step-by-step explanation:
We have,
To find, the value of x in the given equation = ?
∴
By crossmultiplication, we get
3(3x) = x + 16
⇒ 9x = x + 16
⇒ 9x - x = 16
⇒ 8x = 16
⇒ x =
⇒ x = 2
∴ The value of x = 2
Thus, the required value of x is equal to 2.
The number of people of the country which is predicted will be illiterate in the year 2025 are 1,300,700.
<h3>What is percentage decrease?</h3>Percentage decrease is the amount deducted or reduced from the initial value in the percentage part.
In the year 2017, an estimated 4,347,000 people in this country are illiterate. With new incentives and funding, The country is hoping to cut that number by 14% every year.
Total year from 2017 to 2025 are 8 years. Thus, use the following formula of compound interest to find percentage decrease:
Here, A is the final population, The initial population is P, the rate is r and the time period is t. Put the values,
Thus, the number of people of the country which is predicted will be illiterate in the year 2025 are 1,300,700.

The measures of the missing angles in the kite are given as follows:
- Angle A: 116.5º.
- Angle B: 109º.
- Angle C: 69.5º.
The sum of the internal angle measures of a polygon of n sides is given by the equation presented as follows:
S = (n - 2) x 180º.
The kite, as shown by the image at the end of the answer, has 4 sides, hence the sum of the measures is given as follows:
S = (4 - 2) x 180º
S = 2 x 180º
S = 360º.
Angles B and D are on the opposite side of the kite, as shown by the image at the end of the answer, hence they are congruent and:
B = 109º.
Adding the measures, the value of x is obtained as follows:
5x + 14 + 109 + 3x + 8 + 109 = 360
8x = 164
x = 20.5.
Hence the measures are given as follows:
- Angle A: 5(20.5) + 14 = 116.5º.
- Angle C: 3(20.5) + 8 = 69.5º.
The model of the kite, with different angle measures, is given by the image at the end of the answer.
