Sum of the first 8 terms in an arithmetic sequence is 304.
Given that, 
and 
.
<h3>What is sum of arithmetic sequence?</h3>
The sum of the arithmetic sequence formula is defined as the formula to calculate the total of all the terms present in an arithmetic sequence.
The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).
Now, sum of the first 8 terms in an arithmetic sequence is
(8/2).(2+74)
=4×76
=304
Therefore, sum of the first 8 terms in an arithmetic sequence is 304.

Answer:
1: 50 - (3(3) + 5.5(4))=x
2: okay so we know how much books are brought and how much each cost.
In this case paper backs are 3 dollars each and cost 3 dollars each. So 3 (3) is 9 dollars. The next scenario are hardbacks which are 5.50 each and Tom brought 4 of them. So that makes it 5.5(4) which is 22 dollars. So the total would be 9+22 which is 31 dollars. The question asks for change from a 50 dollar bill which you subtract and 50-31=19
The change would be 19 dollars

Combine like terms in Qx + 12 = 13x + P:
x(Q-13) = P-12
P-12
Then x = ----------
Q-13
Note that Q may not = 13. But none of the answer choices present Q = 13.
Let's go thru the answer choices one by one.
P-12
x = ----------
Q-13
-24
Check out A: Q=12 and P= -12: x = -------- = 24 This is OK (ONE sol'n)
-1
-25
Check out B: Q = -13 and P = -13: x = ----------- = 25/26 OK
-26
13-12
Check out C: Q = -13 and P = 13: x = ------------ = -1/26 OK
-13-13
12-12
Check out D: Q = 12 and P = 12: x= ---------- = 0 OK
12-13
It appears that in all four cases, the equation has ONE solution.
You can multiply the digits or the place value. Either way, you will get the same result.
(2 thousands, 7 tens) × 10 =
... (20 thousands, 70 tens)
or
... (2 ten-thousands, 7 hundreds)
