If we want to figure out the ages of Octavia and her brother we will need to check our information.
their ages add up to 39 and her brother is 7 years older than her 
first you will think of all numbers that equal 39; 1+38, 2+37, 3+36, 4+35, 5+34, 6+33, 7+32, 8+31, 9+30, 10+29, 11+28, 12+27, 13+26, 14+25, 15+24, 16+23, 17+22, 18+21,and 19+20
then  eliminate all the numbers that don't have a difference of 7 which will leave the following; the only numbers left are 16 and 23 

so that means that her brother is 23 and Octavia is 16

Semenov [28]
This is a classic example of Scientific Notation. 
5.3 x 10^5 actually equals 530,000
3.8 x 10^4 actually equals 38,000
Since it is asking for the sum of the numbers you are adding.
Your new equation look like this:
530,000 + 38,000 
= 568,000
now all you have to do is count the decimal points. You start from the end zero and count the spaces in between until you get to the tenths place. (Right behind the first number) There are 5
So your answer will be:
 B. 5.68 x 10^5.

9(5x + 1) ÷ 3y
Ivan

Some definitions:

Sum - the result of adding values together

Term - a single number or variable (includes variables multiplied by numbers)

Factor - a number or variable that divides another number or expression evenly

Quotient - the result of dividing values by one another

Coefficient - a numerical or constant value often in front of a variable

In your equation:

Sum - (5x + 1)

5x and 1 are being added together, although we do not know the sum exactly, we know that the sum is equal to the value of 5 times x plus 1.

Term - (5x, 1, 3y)

All terms given above are applicable.

Factor - (9)

9 has been taken out of the expression that it is now being multiplied, which shows that it was factored out of that expression

Quotient - (9(5x + 1) / 3y)

The value of 9(5x + 1) is being divided by 3y. Though we do not know the quotient exactly, we know that the quotient is equal to the values given.

Coefficient - (5, 3)

Both 5 and 3 are numbers in front of variables.

Hope this helps!! :)

Find the distance between the given points (4,1) and (-5, -2)
anyanavicka [17]

Answer:

3\sqrt{10} units I THINK

Step-by-step explanation:

using the distance formula, -2 - 1 = -3

-3 x -3 = 9

-5 - 4 = -9 x -9 = 81

81 + 9 = 90

sqrt 90 simplified is 3\sqrt{10}.

so im pretty sure that's the answer.
