Answers

Answer 1
Answer: so first game
half were eliminated
we notice a pattern
first game=64 times 1/2
next game 32 times 1/2 so

so just multiply by 1/2 till you get 1
round 1 64/2=32
round 2  32/2=16
round 3  16/2=8
round 4  8/2=4
round  5 4/2=2
round 6  2/2=1

6  is the answer

Answer 2
Answer: There are 64 players. For each group, one person is eliminated. You will divide 64/2(the # of people is 64, the number op people in each group is 2). You will get 32. 32 people are remaining. You will, again, divide. 32/2=16. 16 people remain. Divide, again by 2. 16/2=8. Divide by 2 again until you get to 1.

hope this helps!

(4x^2-25)/(2x-5)=14
we hates fractions so m ultiply both sides by (2x-5)
4x^2-25=14(2x-5)
4x^2-25=28x-70
add 70 to both sides
4x^2+45=28x
subtract 28x  fromoth sides
4x^2-28x+45=0
use quadratic formula which is
if you have
ax^2+bx+c=0 then
x=\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}
a=4
b=-28
c=45
subsitute
x=\frac{-(-28)+/- \sqrt{(-28)^(2)-4(4)(45)} }{2(4)}
x=(28+/- √(784-720) )/(8)
x=(28+/- 8)/(8)
x=(5)/(2) or (9)/(2)
if we were to put 5/2 for x, the deonomentor would be equal to zero, so it cannot be used


answer is
x=9/2
