I got 100% on Homework...
The second person must be 20 years old, since that is the median of the ages.
If the mean is 22 years, then the sum when all three added together is 66.
That means, the youngest and the oldest add up to 46 years old.
Let the oldest be x + 16, then the youngest must be x.
x + 16 + x = 46
2x + 16 = 46
2x = 30
x = 15
Since the youngest person is 15, the oldest must be 31.
Hence, the ages, from youngest to oldest, are: 15, 20, 31
Answer:
48 flowers
Step-by-step explanation:
Since, the ratio of tulips to daisies are the same.
Hence, if we have x number of daisies, then the number of tulips will also be x.
Therefore, with number of tulips being 21 and equal ratio of daisies will also mean that Anna has 21 daisies .
The total number of flowers will be :
Number of tulips + Number of daisies
21 + 21 = 42 flowers
Simplify:
3(x - 1) = 8x -3
Expand:
3x - 3 = 8x - 3
Cancel -3:
3x = 8x
Move all terms to one side:
3x - 8x = 0
Simplify 3x - 8 to -5x
-5x = 0
Divide both sides by -5:
x = 0
