What is the answer to this? please show steps also thanks (7.7 x 10^3) x (8.0 x 10^6)

The answer to this question is given below in the explanation section.

Step-by-step explanation:

The question is

(7.7 x 10^3) x (8.0 x 10^6)

Basically, this can be rewritten as

................(1) where * sign represent multiplication

First, we calculate and .

So and

then we put these values (1)

=(7.7 * 1000) * (8.0* 1000000)

=77000 * 8000000

=61,600,000,000‬ answer

Six hundred and sixteen billion.

x=7

Step-by-step explanation:

Simplifying

8 + 2x = 6x + -20

Reorder the terms:

8 + 2x = -20 + 6x

Solving

8 + 2x = -20 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

8 + 2x + -6x = -20 + 6x + -6x

Combine like terms: 2x + -6x = -4x

8 + -4x = -20 + 6x + -6x

Combine like terms: 6x + -6x = 0

8 + -4x = -20 + 0

8 + -4x = -20

Add '-8' to each side of the equation.

8 + -8 + -4x = -20 + -8

Combine like terms: 8 + -8 = 0

0 + -4x = -20 + -8

-4x = -20 + -8

Combine like terms: -20 + -8 = -28

-4x = -28

Divide each side by '-4'.

x = 7

Simplifying

x = 7
