Devaughn's age is three times Sydney's age. The sum of their ages is <br> . What is Sydney's age?
g100num [7]

Answer:

syd is 23 and dev is 69


Step-by-step explanation:

Let Dev's age be x and Syd's age be y

Since Dev is 3 times older than Syd, we may write  

x

=

3

y

Since the sum of their ages is 92, we may write  

x

+

y

=

92

Now replacing x with 3y, we get :  

3

y

+

y

=

92

Hence  

y

=

92

4

=

23

and so Syd is 23 year old.

Back substituting we get Dev is 69 years old.

Rewrite, differentiate and simplify:<br> 3/(2x)^3
Llana [10]

\frac{dy}{dx} = - \frac{9}{8x^{4} }

let y = \frac{3}{(2x)^{3} } = \frac{3}{8} x^{-3}

differentiate using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1}

\frac{dy}{dx} = - \frac{9}{8}x^{-4} = - \frac{9}{8x^{4} }
