If c+1/d=5 , what is the value of 30d/2c+2

klemol [59]

Answer:

3

$d\in R,\hspace{5}d\neq 0$

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

$\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1$

Now, replace the value of c into the other equation:

$\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\$

Using distributive property

$\frac{30d}{10d-2+2} =\frac{30d}{10d} =3$

However, keep in mind that this is true for:

$d\in R,\hspace{5}d\neq 0$
