Find the mean. There will be 6 numbers, so divide by 6

14 = (9 + 12 + 17 + 15 + 13 + x)/6

Simplify

14 = (x + 66)/6

Multiply 6 to both sides

14(6) = (x + 66)/6(6)

84 = x + 66

Subtract 66 from both sides

84 (-66) = x + 66 (-66)

x = 84 - 66

x = 18

18 is your answer for x

hope this helps

The answer to your question would be 15

You find out what the median is (13) and then you look for the bigger number than what your looking for (15) add it to the list then find the median with the set of numbers and 15 then you got your answer

Use the commutative property to create equivalent expressions. Which expressions are equivalent to 2.2t + 3.5 + 9.8? Check all t

aev [14]

The answer is:

$3.5 + 2.2t + 9.8$ (Option 1).

$9.8 + 3.5 + 2.2t$ (Option 4).

$2.2t + 9.8 + 3.5$ (Option 5).

The explanation for this answer is shown below:

1. The commutative property of addtion establishes that if you change the order of the addends, the sum will not change.

2. Let's say that $a$ and $b$ are real numbers, Then they can added them to obtain a result $c$ :

$a+b=c$

3. If you change the order, you will obtain the same result:

$b+a=c$

4. Therefore, the only options that show the applicaction of this property, are the options shown above.

Lynna [10]

For this case, the first thing we must do is define a variable.
We have then:
x: the number of donuts Lee you have purchased
In the morning we have:
2x
In the afternoon we have:
x
Therefore, the total amount that Lee buys is:
2x + x
Answer:
an expression that represents these purchases is:
