Cuanto es 12x + 12 = 12 + 12

lukranit [14]

Answer:

$12x + 12 = 12 + 12 \\ 12x = 12 \\ x = 1 \\ \\ x + 4x = x + 48 \\ 4x = 48 \\ x = 12 \\ \\ 3x + 12 = 24 - 5 + 2x - 1 \\ 3x - 2x = 24 - 12 - 5 - 1 \\ x = 6$

When adding or subtracting with scientific notation,why is it important to have the same power of 10?

sladkih [1.3K]

<h2>Explanation:</h2><h2></h2>

Because we perform something like common factor, so this guarantee that corresponding digits have regarding coefficients have the same place value. Remember that a number written in scientific notation is given by the product of a number between 1 and 10 and another number that is power of 10. For example, let's write two examples about this:

Addition:

$a=2\times 10^3 \\ \\ b=4\times 10^3 \\ \\ \\ Then: \\ \\ a+b=2\times 10^3+4\times 10^3 \\ \\ =(2+4)\times 10^3 \\ \\ =5\times 10^3$

Addition:

$a=2\times 10^3 \\ \\ b=4\times 10^3 \\ \\ \\ Then: \\ \\ a+b=2\times 10^3+4\times 10^3 \\ \\ =(2+4)\times 10^3 \\ \\ =6\times 10^3$

Subtraction:

$a=7\times 10^5 \\ \\ b=2\times 10^5 \\ \\ \\ Then: \\ \\ a-b=7\times 10^5-2\times 10^5 \\ \\ =(7-2)\times 10^5 \\ \\ =5\times 10^5$
