Answer:

Step-by-step explanation:

1. Set up the equation

6(0.18) + 12x = 18(0.08)

2. Simplify

1.08 + 12x = 1.44

3. Solve

12x = 0.36

x = 0.03

0.03 = 3%

Simplify by multiplying 2 (-3x)(-4x +x-7

inna [77]

Hey There.

Hope your well.

2(−3x)(−4x+x−7)

=(2(−3x))(−4x+x+−7)

=(2(−3x))(−4x)+(2(−3x))(x)+(2(−3x))(−7)

=24x^2−6x^2+42x

=18x^2+42x

Hope this helps,

Find the sum of the first 100 terms in the series

iVinArrow [24]

Hello,

$\dfrac{1}{n} - \dfrac{1}{n+1} = \dfrac{1}{n(n+1)} \\

 \dfrac{1}{1*2} = \dfrac{1}{1} - \dfrac{1}{2} \\

 \dfrac{1}{2*3} = \dfrac{1}{2} - \dfrac{1}{3} \\

 \dfrac{1}{3*4} = \dfrac{1}{3} - \frac{1}{4} \\

...\\
 \dfrac{1}{n*(n+1)} = \dfrac{1}{n} - \dfrac{1}{n+1} \\



$

Adding member by member, we have

$\dfrac{1}{1*2} + \dfrac{1}{2*3} +\dfrac{1}{3*4} +...\dfrac{1}{n*(n+1)}=\\
 
\dfrac{1}{1} - \dfrac{1}{n+1} \\

= \dfrac{n}{n+1} \\

$

if n=100 sum $\boxed{= \dfrac{100}{101} }$
