If 13 = 13w/(1-w) ,then (2w)2 =
A.1/4 B.1/2 C.1 D.2
Read Solution (Total 10)
-
- 13=13w/1-w
=>13(1-w)=13w
=>1-w=w
=>2w=1
so,(2w)2=(1)2=2
option D is the answer - 13 years agoHelpfull: Yes(32) No(3)
- 13=13w/1-w
13(1-w)=13w
13-13w=13w
13=26w
w=13/26
now for,(2w)2=(2*13/26)2=2
so the ans. is 2 - 12 years agoHelpfull: Yes(9) No(2)
- 13=13w/1-w
=>13(1-w)=13w
=>1-w=w
=>2w=1
so,(2w)2=(1)2=2 - 10 years agoHelpfull: Yes(4) No(0)
- 13=13w/1-w
=>13(1-w)=13w
=>1-w=w
=>2w=1
so, (2w)2=(1)2 [** here it is 2w^2 and 1^2 **] {unconsciously many of them does it wrong}
=> (2w)2 = 1 [so option C IS CORRECT ] - 6 years agoHelpfull: Yes(4) No(0)
- 13-13w=13w
w= 1/2
2*1/*2 = 2 - 10 years agoHelpfull: Yes(3) No(0)
- 13-13w=13w,
26w=13,
2w=1
so putting the value of 2w in given equition
(2w)*2=2*1=2 - 9 years agoHelpfull: Yes(3) No(0)
- 13w =13(1-w)
w=1-w
2w=1
w=1/2
so,(2w)2 =1 - 9 years agoHelpfull: Yes(1) No(11)
- 13(1-w)=13w
13=13w+13w
26w=13
w=1/2
2(1/2)2=2 - 8 years agoHelpfull: Yes(1) No(0)
- 13=13w/(1-w)
w=1-w
2w=1
(2w)2=2 - 7 years agoHelpfull: Yes(0) No(0)
- if 13= 13w/ (1-w), Then (2w)^2=
solution
13 = 13w/ (1-w) cross multiply
13w = 13(1-w)
13w = 13 - 13w. collect like term
13w + 13w = 13
26w = 13
W= 13/26, = 1/2
substituting W in ( 2W)^2 = (2 x 1/2)^2 ( 2 cancels out = 1
therefore = (1)^2= 1 - 5 years agoHelpfull: Yes(0) No(1)
