Answer:

Step-by-step explanation:

8x + 22 = 19x

Subtract 8x from both sides of the equation

22 = 11x

Divide both sides of the equation by 11

x = 2

Multiply both sides of the equation by 3

3x = 6

Hope this helps :)

Answer:

Step-by-step explanation:

Step 1: Subtract 22 from both sides

8x + 22 - 22 = 19x - 22

8x = 19x - 22

Step 2: Subtract 19x from both sides

8x - 19x = -22 + 19x - 19x

-11x = -22

Step 3: Divide both sides by -11

-11x / -11 = -22 / -11

x = 2

Step 4: Find 3x

Rewrite the following statement using a number in scientific notation.

Mila [183]

Answer:

3.1 x 10^11

Step-by-step explanation:

Since we know that giga means billion, we can piece together that 310 gigabytes = 310 billion

310 billion = 310,000,000,000

When writing in scientific notation, we move the decimal point over until there is only a single digit to the right of the decimal point.

Currently the decimal point is all the way at the end of the 310 billion.

310,000,000,000.

We need to move it over to the left, keeping count of how many times we do so, and stopping when there is only one digit to the right of the decimal.

We end up with: 3.10000000000 or 3.1

We moved the decimal over 11 times. This can be represented by the value 10^11 (pronounced as "10 to the 11th power")

Now, we combine these two to create 3.1 x 10^11

We must multiply the 3.1 by 10^11 in order to create the same amount as 310,000,000,000 (310 billion). If we were to leave 3.1 alone, it would not represent 310 billion.

Thus, we leave this as 3.1 x 10^11 which is scientific notation.

Write in standard form the equation of the line that has a slope of 2 and that passes through ( 3, -1) explain please!

Evgesh-ka [11]

Standard form.

$y=mx+n$

Where m is the slope and n is the point where x=0. Then, you have,
$y=2x+n$

To obtain n use the point they give you,

$-1=2(3)+n$

So n=-7 and then

$y=2x-7$
