Answer:
We need to find 5 + 10 + 15 + ... + 485 + 490 + 495. There are 99 numbers that are being added. To add this we can do 5 + 495, 10 + 490, 15 + 485 and so on. These pairs have a sum of 500 and since there are 98 / 2 = 49 pairs their sum is 500 * 49 = 24500. Since there is an odd number of numbers that are being added, there is one number that does not belong to a pair. That number is the 50th number in the list which is 50 * 5 = 250. Therefore the answer is 24500 + 250 = 24750.
Answer: A
Step-by-step explanation: gcf = 7
Grouping: 7((x+2)(x-2))
We put this into an algebraic equation, where <span>x = the number .
x + 17 > 26
x > 9
This </span>> is the greater than sign, we use this because it's no less than 26.
Ideally we would use this sign:
<span>http://etc.usf.edu/clipart/41700/41712/fc_greateq_41712_md.gif
because it could be equal to 26.
</span><span>The number is <u>greater or equal to 9</u>
