    First:
    Answer: B = 1955

    [(143*5 + 67) * 5] / 2 = [(715 + 67) * 5] / 2 = 3910 / 2 = 1955

    Second:
    Answer: A X= .5

    After - cancelation it remains
    -10x = -5 <=> 10x = 5 => x = .5

    Third
    Answer: Tricky :-) (depends how you look at it)

    But, i choose this one -> Solution 1 = B. False

    Solution 1: B. FALSE
    Reason: 10 * 3 = 150 <=> 30 = 150 => false

    Solution 2: A. TRUE
    If it is taken as multiply, the answer is simple because its only multiplication and N being present in both sides, also N = 0 => 0 = 0 - true

    1435 =715
    715+67 = 782
    782    5 = 3910
    3910/2 =1955

      A. X=.5
      minus sign is cancel out and 5/10 = 0.5

      A. True
      because N = 0, I get 0 x 3 = 0 which is true.

      first Q
      [(143x5+67)5]/2 =
      ((782)5)/2

      Answer is B (1955)

      2nd Q
      [-(-(-)(-)(-10x))]=-5

      there are 5 minus signs. -10x=-5
      x = 0.5
      the answer is A

      3rd Q
      AN times E equals ABN A=1 B=5 E=3 N=0

      AN=1x0=0
      ANxE= 0x3=0
      AxBxN=1x5x0=0

      ANE=ABN=0

      the answer is A true

        1, 1435=715+67=7825=3910/2=1955
        2, (-10.5) = [-(-(- )(- ) -5] =- 5. eg -- = +,-*+ = -.
        3, false,upvoted

          #1 B-1955
          #2 A-x=.5
          #3 B-False (because the letters are symbols. So they don't multiply when the multiplication symbol is not there. So AN=10, AN *E= 30, ABN = 150. So they are not equal therefor it's false)

            1. 1955, because Punkt-vor-Strich
            2. X =0.5 because minus times minus equals plus and minus times plus equals minus
            3. false because 10x3 != 150

            tataa I am a math god;-)

            PS: You should make it a rule to send the answer to you via a money transfer. The trick is that when you add a # before the message which you can send with the money, it will b invisible to others.
