180 but i dont know if thats exactly right my friend
just told me so its probably not even right
Answer:
An annual increase of 3.24% of the population.
Step-by-step explanation:
The population did not increase by the same number each year, because:
First 5 years:
1000 - 1162 = 162 people
Second 5 years:
1350 - 1162 = 188 people
Third 5 years:
1568 - 1350 = 218 people
What it says is that numerically the same number of people did not increase every 5 years, but if I increase by the same percentage, to calculate this percentage we divide the new people by the number that there were originally, that is to say:
First 5 years:
162/1000 = 0.162 = 16.2%
Second 5 years:
188/1162 = 0.1618 = 16.2%
Third 5 years:
218/1350 = 0.1615 = 16.2%
Which means that per year I increase by:
16.2 / 5 = 3.24%
Answer:
5
5.7
7.1
6.9
Step-by-step explanation:
|4 - 9| = 5
|-3.1 + 8.8| = 5.7
|-7.1| = 7.1
|2.7 + 4.2| = 6.9
Answer: 3
Step-by-step explanation:
Let the smaller number be y.
Since the difference of two numbers is 5,then the larger number will be: y+5
The sum of three times the larger number and twice the smaller number is 30. This can be written as:
3(y+5) + 2y = 30
3y + 15 + 2y = 30
5y + 15 = 30
5y = 30 - 15
5y = 15
y = 15/5
y = 3
The smaller number is 3
This question is a simple answer just combine the like terms.
Your final answer is: 3x+2y+2
