Think that I borrowed $1000 from a person and $500 from another person. While i was going home a lost $1000. So the balance $500. From the $500 and spend $300 on fish. So the balance is $200. I split the money into 2 parts ( 100 and 100 ) and gave one part to the person who gave me $1000 and one part to the person who gave me $500. So the total money I have to give back = 1000-100+500-100=900+400=1300. So 1500-1300=200. So the question is 300( which i used for fish)-200( the balance) = 100. From where did I get the $100 ?

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
