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.

julsineya [31]
Hey there

Lets solve this question together, 

Convert <span>76.8%</span><span> to a decimal.
</span>
0.768 * x=40.32 

Multiply 0.768<span> by </span>x<span> to get </span><span>0.768x</span><span>. 
</span>
&#10;0.768x=40.32 

Multiply<span> each </span>term<span> by </span><span>1 / 0.768</span><span> and simplify.
</span>
Cancel the common factor of 0.768.

x=40.32 / 0.768 

Divide 40.32<span> by </span>0.768<span> to get </span><span>52.5 

</span>x=52.5 <span>
</span>
