If a = 1/x+1/y , what is the value of 1/a
lana66690 [7]
<h3>Solution</h3>

a=\frac{1}{x}+\frac{1}{y}

so the value of 1/a is…

\begin{aligned}\frac{1}{a}&=\frac{1}{\frac{1}{x}+\frac{1}{y}}\\&\Rightarrow\frac{1}{\frac{y+x}{xy}}\\&\Rightarrow1\times\frac{xy}{y+x}\\&\Rightarrow\frac{xy}{x+y}\end{aligned}

A class voted for either rollerblading, swimming, or biking as their favorite summer activity. If rollerblading got 27% percent
emmasim [6.3K]

Answer:

All you have to do is find the rest of the percentage. Percentage adds up to 100%. So you will have to add the two percentages they gave you. 27+33=60%. Now you have to take away 60 from 100. 100-60=40%.

40%- That's the answer.

Hope this helps.
