Can some one translate the sum of a number and twice the its reciprocal is 3?
A number . . . ' x 'Its reciprocal . . . 1/xTwice its reciprocal . . . 2/xThe sum of (the number) and (twice its reciprocal) . . . x + 2/xThe equation:x + 2/x = 3Multiply each side of the equation by 'x' :x2 + 2 = 3xSubtract 3x from each side:x2 - 3x + 2 = 0Factor the left side, in order to see what's going on:(x - 1) (x - 2) = 0This is true if 'x' is either ' 1 ' or ' 2 '.x = 1The sum of the number and twice its reciprocal . . . 1 + 2/1 = 3X = 2The sum of the number and twice its reciprocal . . . 2 + 2/2 = 3
What is the math property when you are multiplying a reciprocal to equal 1?
== The sum of any number and zero is that number.(2+0== 2) == the sum of any number and zero is that number. (2+0=2)
What does find the repirocal of each number mean?
Say, find the reciprocal of 2 = 1/2 Reciprocal of 1/2 = 2
What is the reciprocal of two?
The reciprocal of 2 is 1/2 (one-half). The reciprocal of any number is 1/number. Simply stated: The reciprocal of any number is the inverse of that number. Let some number, any number, be represented by 'a'. The reciprocal of 'a' is 1/'a'.
The sum of two numbers is 10 and their product is 20 find the sum of the reciprocal of the number?
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
