Step-by-step explanation:
Answer: 82.5 - x = R sorry if I am wrong
Step-by-step explanation:
1. We know all the angles in a triangle add up to 180 degrees.
<em>180 = x + x + 15 + R</em>
2. Combine like terms
<em>180 = 2x + 15 + R</em>
3. Subtract 15 from both sides
<em>165 = 2x + R</em>
4. Divide both sides by 2
<em>82.5 = x + R</em>
5. Subtract x from both sides
<em>82.5 - x = R</em>
Answer:
It sucks
Step-by-step explanation:
Answer:
≈ 13.98%
Step-by-step explanation:
As the total population is 5769 in the initial period, you must find the percentage that repesents 4963 that is the expected population.
4963/5769=0.8602
Then you multiply it by 100 to transform it into percentage
0.8602*100=86.02%
Then it's just necesary to subtract that from 100% and that numbers is the percentage of decrease
100% - 86.02% = 13.98%
Also you can say that is approximately 14%
