This is an arithmetic series with common difference 6
S13 = (13/2)[2*-5 + (13-1)*6)] = 403
Ok, so...what is the question?...
<span>Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.
(1 - 0.12) y (1 + 0.06)</span>
Set up the equation:
x=(3x-70)
0=2x-70
2x=70
x=35
Now to find LMN we plug it back in:
3(35)-70=35
Final answer: 35 degrees
:)
The answer is 37/100 as a fraction. Hope this helps you.
