The population increases by 500 each year, so multiply the number of years that have passed since 1990 by 500.

1999 - 1990 = 9 years

9 years * 500 = 4,500

Add 4,500 to 22,317 inhabitants.

22,317 + 4,500 = 26,817

Your answer is B) 26,817 inhabitants.

There were twelve times more children than adults at the matinee performance of the school play. There were 455 people at the pl
____ [38]

Answer:

35 adults, 420 children

Step-by-step explanation:

1. Set up variables

Let's say children is c and adults is a.

2. Create the equations

c = 12a AND c + a = 455

3. Plug in the variables

Let's take c = 12a and substitute it in for c in the equation "c + a = 455." That would be...

12a + a = 455

13a = 455

a = 35

3. Plug in more variables

Now we have our answer for a, so let's plug it into the other equation. That would be...

c + a = 455

c + 35 = 455

c = 420

Answer:

  1 5/24 + 7 22/24 = 8 27/24

Step-by-step explanation:

No change is required to the fraction on the first line:

  1 5/24 = 1 5/24

The fraction on the second line can be multiplied by 2/2 to make its denominator 24.

  7 11/12 = 7 22/24

The fraction on the third line is the sum of the fractions on the other two lines. It is an improper fraction. We know this because the integer portion of the sum is shown as 8, not 9, as it would be if the fraction were reduced.

  5/24 +22/24 = 27/24

Then the sum is ...

  1 5/24 +7 22/24 = 8 27/24

_____

If the fraction on the final line were reduced, the sum would be 9 3/24 = 9 1/8.
