Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?

SVEN [57.7K]

Answer:

x=42

Step-by-step explanation:

2(x-8)=68

Distribute the 2

2x-16=68

Use the addition property of equality (add 16 to both sides)

2x=68+16

2x=84

Use the division property of equality (divide both sides by 2)

x=84/2

x=42

Phoenix [80]

Answer:

Step-by-step explanation:

$i-\text{imaginary\ unit}\\\\i=\sqrt{-1}\to i^2=-1\\\\=====================$

$\dfrac{10-10i}{-5i}=\dfrac{10}{-5i}+\dfrac{-10i}{-5i}=\dfrac{(10)(i)}{(-5i)(i)}+2=\dfrac{10i}{(-5)(i^2)}+2\\\\=\dfrac{10i}{(-5)(-1)}+2=\dfrac{10i}{5}+1=2i+2=2+2i$

You start a chain email and send it to six friends. The next day, each of your friends forwards the email to six people. The pro

Elina [12.6K]

Solution:

The following information about the chain email can be Written as follows:

1 Person Email →→6 Persons (E-mail) →6² Persons (E-mail)→6³ Persons (E-mail)+.........few Days

As you can see the number of email sent starting from person 1 to 6 persons to 36 persons to 216 persons, forms a Geometric pattern.

So, Sum of the Series = 1 + 6 + 36 + 216 + 1296 +......+ for n days

= $1+6^1+6^2+6^3+6^4 +6^5 +6^6+..........+ 6^n$

Formula for n terms of a geometric series

$\frac{a (r^n-1)}{r-1}$

For, Common ratio (r)≥1

Sum of above geometric series up to n terms $=\frac{6^n-1}{6-1}=\frac{6^n-1}{5}$
