6.247 * 10 to the twelfth power in standard form
Scrat [10]

Answer: 6,247,000,000,000

Step-by-step explanation:

Here we have the number:

6.247x10^12 and we want to write this in standard form.

You can see that we have a 10^12, this means that we need to move the decimal dot 12 places to the right, if there is not a decimal to the right, we add a zero.

6.247x10^12 = 62.47x10^11 = 624.7x10^10 = 6,247x10^9 = 62,470x10^8 and so on.

eventually, the standard form is:

6.247x10^12 = 6,247,000,000,000

So we end with 12 digits after the six.

Solve the system using elimination.
Zarrin [17]

<u>The solution is (1,2)</u>

Step-by-step explanation:

 7x + 10y = 27

 x - 10y = -19                                                                                                                    +--------------------

8x = 8

Divide by 8 on both sides

x = 1

To find y substitute any of the equations to 1

7(1) + 10y = 27

7 + 10y = 27

Substract 7 from both sides

10y = 20

Divide by 10

y = 2
