Answer:
12 cows - 48 legs
4 ducks- 8 legs
- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.
Step-by-step explanation:
22 total animals
56 total legs
ducks have 2 legs
cows have 4 legs
12 times 4 = 48 ( 12 cows with 4 legs each cow = 48 legs)
4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)
Answer:
a+4b-24
Step-by-step explanation:
You have to multiply the entire equation by 4, which get you a+4b-24
Your answer would be option C. x² + y² + 6x - 24y + 128 = 0.
This is because the formula for the equation of a circle is (x - [x coordinate])² + (y - [y coordinate])² = radius², so you have to substitute in the coordinates and the radius, and then expand and simplify. I have done this in paper as it is easier to write than type, but let me know if you would like me to explain any part of it.
I hope this helps!
The answer is B. 2x + y = 24 ; 2x - y = 12. Solution: (9,6)
This is easily answered by translating the given worded statements into their mathematical form. Sum refers to the addition of two terms, and difference refers to the subtraction of two terms.
Substituting the given solution set, the equations are proven to be correct.
