\frac{1}{6} + \frac{1}{12}


We know that:


\frac{a}{b} + \frac{c}{d} = \frac{a.d + b.c}{bd}


So,


\frac{1}{6} + \frac{1}{12} = \frac{1.12+6.1}{6.12}

\frac{12+6}{72}

\frac{18}{72}

\frac{9}{36}

\frac{3}{12}

\frac{1}{4}

If y varies directly as​ x, and y=8 when x=3​, find y when x=15.
Crank

Answer:

y=40

Step-by-step explanation:

The formula for Direct Variation is y=kx or k=y/x. In this case I would use k=y/x. If you're y is 8 and x is 3, this means that K=8/3. Using this, we know that X=15. We have to find a Y value so that the fraction with an x of 15 simplified is 8/3. To do this you would write 8/3 and y/15. Now cross multiply to get 3y=120. Divide by 3 to get y=40.
