Question

what's the sum of all integers -700 to +705​

Answer 1

Answer:

Here we will use algebra to find three consecutive integers whose sum is 705. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 705. Therefore, you can write the equation as follows:

(X) + (X + 1) + (X + 2) = 705

Step-by-step explanation:

To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:

X + X + 1 + X + 2 = 705

3X + 3 = 705

3X + 3 - 3 = 705 - 3

3X = 702

3X/3 = 702/3

X = 234

Which means that the first number is 234, the second number is 234 + 1 and the third number is 234 + 2. Therefore, three consecutive integers that add up to 705 are 234, 235, and 236.

234 + 235 + 236 = 705

We know our answer is correct because 234 + 235 + 236 equals 705 as displayed above.

Answer 2

Step-by-step explanation:

Therefore, three consecutive integers that add up to 705 are 234, 235, and 236. We know our answer is correct because 234 + 235 + 236 equals 705 as displayed above.
