Answer:
There are 20 ducklings.

For every group of 6 ducks, 5 would be ducklings.
24 / 6 = 4
There are 4 groups of ducks.
5 * 4 = 20
Answer:
x = 20°
Step-by-step explanation:
The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.
3x + 2x simplifies to 5x. 5x must equal 100.
100/5 = 20.
Therefore x = 20.
5 and 2/3 because 51/9= 5.666666667, which .66666667 in fraction form is 2/3
The answer is 155 . 234-79=155 !
