Answer:
r = -3
Step-by-step explanation:
Performing the indicated multiplication on both sides of this equation, we get:
5r - 5 = 2r - 8 - 6
Combining the r terms: 3r - 5 = - 8 - 6.
Combining the constants: 3r = 5 - 14, or 3r = -9.
Dividing both sides by 3, to isolate r, we get: r = -3
Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
13x + 34° + 10x + 10° = 90°
=> 13x + 10x = 90° - 34° - 10°
=> 23x = 46°
=> x = 46°/23 = 2°

To calculate growth rate, start by subtracting the past value from the current value. Then, divide that number by the past value. Finally, multiply your answer by 100 to express it as a percentage.
<u>Explanation:</u>
The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Annual Growth Rate of Population refers to the rate at which the number of individuals in a given popular increase over a year, expressed as a fraction of the initial popular of the previous years. The annual percentage growth rate of population is the percent growth divided by the number of years.
