Answer:
The answer is 25%
Step-by-step explanation:
on the first year lets say town A and town B had a population of 100 (a town wouldn't have only 100 people but for simplicity lets do 100).
town A's population increases by 60%, 60% of 100 is 60, 100 + 60 = 160
town B's population decreases by 60%, 100 - 60 = 40
so now we have town A's population after 10 years and town B's population after 10 years, 160 divided by 40 = 4, and 100 divided by 4 equals 25, so the answer is 25%.

The irrational number that represents the length of each side of the squares is 6.7082039324993 units.
In turn, since the upper side of the rectangle is twice the side of the square, the sides of the rectangle measure 6.7082039324993 units and 13.416407864998 units.
Since the length of a rectangle is twice the width, and the area of the rectangle is 90 square units, noting that the rectangle can be divided into two squares, to determine which irrational number represents the length of each side of the squares, and estimate the length and width of the rectangle, the following calculations should be performed:
- Rectangle = 90 square units
- Square = 45 square units each
- X ^ 2 = 45
- X = √45
- X = 6.7082039324993
- Therefore, the irrational number that represents the length of each side of the squares is 6.7082039324993 units.
- In turn, since the upper side of the rectangle is twice the side of the square, the sides of the rectangle measure 6.7082039324993 units and 13.416407864998 units (6.7082039324993 x 2).

It is a, if you plug it in, it works. 10=3*3+1 is true.
<span>Amelia + Bernard + Cindy = 10w {the total of their ages is 10w}
2w + ? + ? = 10w {Amelia is 2w years old, Bernard and Cindy are the same}
? + ? = 8w {subtracted 2w from each side}
2? = 8w {added ? and ?}
? = 4w {divided each side by 2}
Cindy is 4w
</span><span>If w = 4,
4w
= 4(4){substituted 4 in for w}
= 16 {multiplied}
If w = 4, then Cindy is 16</span>
