Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
Hey there!!
Let's take the two numbers as 'x' and 'y'
The sum of these two numbers is 36.
... x + y = 36
Twice the first number minus the second is 6.
... 2x - y = 6
Now, we have two equations.
_______________________________________________________
... x + y = 36
... 2x - y = 6
Now, let's add both the equations.
... 3x = 42
Divide each side by 3.
... x = 42 / 3
... x = 14
<em>Hence, the first number is'14'. </em>
We know the sum of both the numbers is 36.
... x + y = 36
... 14 + y = 36
Subtract 14 on both sides.
... y = 36-14
... y = 22
<em>Hence, the second number is 22. </em>
<em>The numbers are 14 and 22. </em>
Hope my answer helps!!
