Answer:
The answer for your question is 2.
Step-by-step explanation:
Correct Answer: - 550
We can use the distributive property to distribute the summation to the variables and then get the constant out to apply the summation formulas as shown below in the attached image.
The equation editor does not have a summation symbol, so I have attached the solution using the image.
The correct answer to this question is -550. First option is the correct one.
The answer should be 23. Not sure if you have multiple choices, or have to show the work, but 23 is the answer.
Put in a equality
20 > (70/x)
then you solve
20x > 70
x>70/20
x> 3.5 you can not put part of a chair in a row so you round up
****You can put 4 or more chairs in a row****
Eliminate the exponent
2^3=8
9^3=729
The simplified answer would be 8/729.
Hope this helps!
