500= 120+20x, where x is weeks
Subtract 120 from both sides
380=20x
Divide both sides by 20
19=x
19 weeks*7 days per week= 133 days
Final answer: 133 days
The size of the population increases when the growth rate is positive and
decreases for a negative growth rate.

The population in growth rate is given by the following formula;
P = a·(1 + r)ˣ
Where;
a = The initial population in 2003 = 40.5 million
P = The population in 2029 = 20.9 million
x = The number of years = 2029 - 2003 = 26
Therefore;
20.9 = 40.5 × (1 + r)²⁹
The population growth rate is r ≈ -0.02255 = -2.255 %
The completed table is therefore;

Answer: B
-14 - 2x - 10 + 3y + 8x - 16y
Put everything in order so it is easy to combine like terms.
-2x + 8x + 3y - 16y - 14 - 10
Combine like terms. That means that you should add both x's together, add both y's together, and add both numbers together.
6x - 13y - 24
B is your answer! If you are confused on why B looks different, it is becuase the variables/numbers are in mixed up places. I hope this helps you!
Answer:
Step-by-step explanation:
5 miles + 16 miles = 21 miles
each mile is 2.50
21 x 2.50 = 52.50
trip is 4.50
52.50 + 4.50 = 57
