If a number is added yo the numerator of 12/43 and twice the number is added to the denominator of 12/43 the resuliting fraction
DaniilM [7]

Answer:

The number is 7.

Step-by-step explanation:

In this case we have an unkown variable that is a number. We will call this number by "x", this is what we want to calculate. In the first part it is said that the number or x is added to the numerator and in the second part it is said that twice the number is added to the denominator, and that this fraction is equal to 1/3. So we have:

1/3 = (12 + x)/(43 + 2*x)

43 + 2*x = 3*(12 + x)

43 + 2*x = 36 + 3*x

43 - 36 = 3*x - 2*x

x = 7

The number is 7.

If a/\2+1/a/\2=11, then a+1/a=?
Nadya [2.5K]

Answer:

\pm \sqrt{13}

Step-by-step explanation:

\bigg(a +  \frac{1}{a}  \bigg)^{2} =  {a}^{2}   +  \frac{1}{ {a}^{2} }  + 2 \times a \times  \frac{1}{a}  \\  \\ \bigg(a +  \frac{1}{a}  \bigg)^{2} = 11 + 2 \\  \\   \bigg(a +  \frac{1}{a}  \bigg)^{2} = 13 \\  \\  \bigg(a +  \frac{1}{a}  \bigg) =  \pm \sqrt{13}
