What is the sum of all possible multiples of 5 less than 500
Leona [35]

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.

A little help would be nice
Katena32 [7]

Answer:

13). -2x³ + x² + 1   14). x + 10y - 10z   15). -2x³ + x² + 1

Step-by-step explanation:

13). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² - 3 + 4

= -2x³ + x² + 1

14). (3x + 4y - 3z) - (2x - 6y + 7z)

= 3x + 4y - 3z - 2x + 6y - 7z

= 3x - 2x + 4y + 6y - 3x - 7z

= x + 10y - 10z

15). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² + 4 - 3

= -2x³ + x² + 1
