The answer for this problem is -8x+2
1 ton= 2,000 pounds
250 x 8 = 2,000
final answer: it would take the elephant 8 days to eat a ton of food

Answer:
x=-3
y=2
Step-by-step explanation:
To solve this problem you can use the elimination method:
- Multiply the second equation by -6:
- Add both equations:
- Substitute the value of x into one of the original equations and solve for y:
Answer:
25 percent
Step-by-step explanation:
to get percent you need a fraction of something over a hundred. To get there, you simplify this to 1/4, then go to 25/100, so 25%
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
