Answer:
There are 20 ducklings.
Step-by-step explanation:
For every group of 6 ducks, 5 would be ducklings.
24 / 6 = 4
There are 4 groups of ducks.
5 * 4 = 20
Answer:
7
Step-by-step explanation:
"a certain whole number" is a number that we don't know, so pick a variable, let's use n
"Twice" means two times, so we'll use 2n for this.
"subtracted from" means the 2n will be AFTER the minus sign.
____ - 2n
What goes in front? "3 times the square of the number" 3n^2
Now we have 3n^2 - 2n
Lastly, we see the result is 133. So this gives us:
3n^2 - 2n = 133 To solve, subtract 133 from both sides of the equation.
3n^2 -2n - 133 = 0 Next FACTOR.
(3n + 19)(n - 7) = 0
3n+19=0 and n-7=0
n=-19/3 and n=7
Since we are looking for a whole number choose n=7
Answer:
slope = 
Step-by-step explanation:
1) Calculate the slope using slope formula, 
. Use the two points given, substitute their x and y values into the formula, and solve.
Thus, the slope is .
The correct response is X=25
