lbvjy [14]

Answer:

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.2%/100 = 0.042 per year,

then, solving our equation

I = 16500 × 0.042 × 5 = 3465

I = $ 3,465.00

The simple interest accumulated

on a principal of $ 16,500.00

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

klemol [59]

Answer:

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

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:

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