What is the reciprocal of a number plus the reciprocal of twice the number equals three over ten?
Let the number be x: 1/x+1/2x = 3/10 Multiply all terms by x: 1+1/2 = 3x/10 Multiply all terms by 10: 10+5 = 3x 15 = 3x Divide both sides by 3 to find the value of x: x = 5

What is the reciprocal of a number plus the reciprocal of twice the number equals three over ten?
Let the number be x: 1/x+1/2x = 3/10 Multiply all terms by x: 1+1/2 = 3x/10 Multiply all terms by 10: 10+5 = 3x 15 = 3x Divide both sides by 3 to find the value of x: x = 5

The reciprocal of a number plus the reciprocal of twice the number equals one half?
Let the number be x.Reciprocal of x = 1/xReciprocal of x + Reciprocal of 2x = 1/x + 1/(2x) = (3/2)x = 1.5xIf the value of x = 1/3 then answer is one half.If the value of x = 2 then answer is 3.So, the statement is true only for x = 1/3.___________1/x + 1/2x = 1/2Multiplying both sides of the equation by 2x gives:2x/x + 2x/2x = 2x/2This simplifies to:2 + 1 = xx = 3 (i.e. the reciprocal is 1/3)
