Answer:the first term is 6
Step-by-step explanation:
We would apply the formula for determining the sum of n terms of an arithmetic sequence. It is expressed as
Sn = n/2(a + l)
Where
n represents the number of terms in the arithmetic sequence.
l represents the last term in the arithmetic sequence.
a represents the first term in the arithmetic sequence.
From the information given,
l = 204
n = 12
Sn = 1260
We want to determine a. Therefore,
1260 = 12/2(a + 204)
1260 = 6(a + 204)
a + 204 = 1260/6 = 210
a = 210 - 204 = 6
Answer:
oop wait a second im learning this too lol
ummmmmmm ahhhhhhh
Step-by-step explanation:
Answer:
y = -12
Step-by-step explanation:
-7/3y - 2/9 = 1/3
cross multiple for 1/3:
-21/3y - 6/9 = 1
cross multiply for 3y and 9:
-21 - 6 = 3y + 9
3y + 9 = -27
3y = -36
y = -12
When you need to round a number. First you need to look at the placement number that the question is asking to round to the nearest. In this case it's the nearest hundred.
3,130,<u>6</u>49 the 6 is in the hundreds place. Now look to the number to the right of that number 3,130,6<u>4</u>9 that's the number that tells you if you will round up or down. If the number is 5 or more you round up, if it's less than 5 you round down.
In this case the 4 is less than 5 so you round down.
So your answer would be <u>3,130,600</u><u />
Hope this helps. :)
