Answer:
finding the product of 9,10,and 9
810
Step-by-step explanation:
Estimated round up $6000 and divide by $30(rounded up) = $200 each estimated
$5820÷28= $207.857.. so round up to $208
2/3(4x - 5) = 8...divide both sides by 2/3, eliminating the 2/3 on the left
4x - 5 = 8/(2/3)
4x - 5 = 8 * 3/2.. dividing with fractions, flip what u r dividing by, then multiply
4x - 5 = 12....add 5 to both sides, eliminating the 5 on the left
4x = 12 + 5
4x = 17 ...divide both sides by 4
x = 17/4 or 4 1/4
We call:
as the set of <span>the first 51 consecutive odd positive integers, so:
</span>
Where:
<span>and so on.
In mathematics, a sequence of numbers, such that the difference between two consecutive terms is constant, is called Arithmetic Progression, so:
3-1 = 2
5-3 = 2
7-5 = 2
9-7 = 2 and so on.
Then, the common difference is 2, thus:
</span>
<span>
Then:
</span>
<span>
So, we need to find the sum of the members of the finite series, which is called arithmetic series:
There is a formula for arithmetic series, namely:
</span>
<span>
Therefore, we need to find:
</span>
Given that
, then:
Thus:
Lastly:
