1/(x-5) = 4/(2x)
4(x-5) = 2x
4x - 20 = 2x
2x = 20
x = 10
_______________________________
Check:
1/(10-5) ?=? 4/(2x10)
1/5 ?=? 4/20
1/5 = 1/5 yay!

One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
The number is 7.
Ok, so let x be the number and write the word phrase as an equation.... 1/(x-4)=2(1/x) 1/(x-4)=2/x Flip them... x-4=x/2 times 2... 2x-8=x move the x, so... x=8 And your welcome ^-^ (asian brain power)
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
6x -5 < 2x +10

When a number is a fraction, the reciprocal will always be greater than the original number. When the original number is a whole number, the reciprocal will be a fraction, which is less than a whole number.

Suppose the number is x. Then 1/(x-5) = 4*(1/2x) Multiply both sides by x*(x-5) to give: x = 4*(x-5)/2 = 2*(x-5) = 2x - 10 and so x = 10
The answer is 6.

Reciprocal of any non - zero number [other than 1 (because reciprocal of 1 is 1)]is always less than '1' .============================The first contributor disputes the change:Sorry, Anu. What about the non-zero number 0.5, whose reciprocal is 2 ? ? ?

Twenty more than twice a number is 52
the quotient of twice a number and six is.... 2x/6 four less than three times the same number is .... 3x-4 So the equation would be 2x/6=3x-4
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
