The answer to this equation is 18x+18=8x+18. This would NOT be infinite solutions because 18x and 8x do not have the same value. So, I believe it would be one solution.

What is the sigma notation for this arithmetic series : 10+25+40+...+490+505

Lubov Fominskaja [6]

Answer:

Sum (from n = 0 to n = 33) of 10 + 15 * n

Step-by-step explanation:

The sigma notation is to express an arithmetic series as a summation, in this case we can see that it starts at 10 and ends at 505.

What we can notice is that the values are increasing by 15 units, therefore that will be the proportion that accompanies "n".

Now, we must calculate, how many times is "n", in the final value, for this we subtract the initial value, that is 10 and divide it by 15.

505 - 10 = 495/15 = 33

So "n" goes up to 33

So that series is expressed like this:

Sum (from n = 0 to n = 33) of 10 + 15 * n

Andrews [41]

Finding the difference between the two temperatures, it is found that Regina is 38.7ºC degrees colder in January than in July.

----------------------------

The mid-afternoon temperature in January is of -12.6ºC.
In July, it is of 26.1ºC.
The difference of the temperatures is given by:

$26.1 - (-12.6) = 26.1 + 12.6 = 38.7$

From the difference of 38.7ºC, there are two interpretations:

Regina is 38.7ºC degrees colder in January than in July.
Regina is 38.7ºC degrees warmer in July than in January.
