He bought 7 eggs. @AK: 4x-7=48 x= 55/4 MARC2008:Can I get the points?;) (x-2)(x+1)/ x=2, x=-1 Puzzle:1 egg [edit] difficulty: medium [3P] factorise: x^2-5x+50 [edit] I mean x^2+5x-50 [re-edit] also here's a puzzle(hard, 7P): there's a house and a market with 3 toll bridges between them a man goes to the market, he doesn't have to pay to cross the bridges on the way there. he buys x eggs, but has no money left so to pay the toll bridge fee he pays half the eggs in his basket plus half an egg. he has no eggs after rossing them all. what is x?  =10.25 or 10 1/4 or 41/4 New question(4p); 4x-7=48 x= Keep in a fraction! At least then I know its 5.3662479...  I think I'm more accurate. 
How many points do I get? I also realised I work at 2-3 times the speed of my class XD [edit] may I ask a question? Next:(6p) t^2-4t+7=0 Use the quadratic formula and solve for both values of t! THERE ARE NO JOKERS IN A 52-CARD DECK! Next question(2p): 56-42 Um... Points to both MARC and Allyally.... WORD PROBLEM!!!!!!!!(15p): You take a standard 52 card deck. You want to play a game called "4 Aces and 2 Jokers". You put all 52 of the cards face down on the table. What is the probability that you will pick all 4 aces before you pick 1 joker??? You actually don't need it in simplest form. | GeneralFirst post of the topic Here we go! First question(1p) 6-2=?

t^2 - 4t + 7 = 0
You'll quickly notice that this parabola has no real solutions: the solutions are therefore two different imaginary solutions.
t = 2 + i*1.73205 V t = 2 - i*1.73205
(V = or)
