Answer:
b. 3.775
Step-by-step explanation:
The question is worded incorrectly since the sum of the first 100 counting numbers is actually greater than the sum of the first 50 counting numbers.
The sum of any set of consecutive numbers of size 'n' is given by:
Where A1 is the first number on the set and An is the last number.
The sum of the first 100 counting numbers (1 through 100) is:
The sum of the first 50 counting numbers (1 through 50) is:
The difference between those two values is:
Therefore, the sum of the first 100 counting numbers is 3,775 greater than the sum of the first 50 counting numbers.
Is this all there is to the question????
Answer:35 dollars each
Step-by-step explanation: Because if you take the $40 out of 180 you get 140 then you divide 140 by 4 and you get 35. Hope this helps.
It’s 0.170 that’s rounded
Alright, 1, 2, and 4 are correct but 3 is not.
The error you made could be hard to notice but it was made. So let's put the equation up, 6x-(2x-9)=-31. Your error occurred when you didn;t distribute the negative sign for (2x-9), if you woud have distributed it then the equation would then be simplified into 6x-2x+9=31. You then add like terms and get 4x+9=31, subtract 9 on both sides and you'll get 4x=22. Divide 4 on both sides to isolate the variable and you get x=5.5
