Answer:

x=25

Step-by-step explanation:

Given Equation:

4x-3(x+5)=10

Solving the equation for 'x'

4x-3(x)-3(5)=10\\\\4x-3x-15=10

Solving the like terms:

x-15=10

Adding '15' both sides:

x-15+15=10+15\\\\x=10+15\\\\x=25

The solution of the equation is: x=25

From 1980-1990, the population of a country was increased by 20%. From 1990-2000, the population of the country was increased by
Mrac [35]

Answer:

The % of the increase in population from 1980 to 2000 will be 72.8%

Step-by-step explanation:

Let the population in the year of 1980 was x.

If the population from 1980 to 1990 has increased by 20%, then the population in the year 1990 will be x(1 + \frac{20}{100}) = 1.2x.

Now, from 1990 to 2000, the population has again increased by 20%.

So, the population in the year 2000 will be 1.2x(1 + \frac{20}{100}) = 1.44x.

Again, from 2000 to 2010, the population has increased by 20%.

Therefore, the population in the year 2010 will be 1.44x(1 + \frac{20}{100}) = 1.728x.

Now, the population increased from x to 1.728x between the years 1980 to 2010.

Hence, the % of the increase in population from 1980 to 2000 will be (\frac{1.728x - x}{x}) \times 100\% = 72.8\% (Answer)
