lets use A as the variable for pages in the algebra book since there is none given for how many are in the algebra book
the best equation would be A-99=n
hope this helps
Both pairs of vertical angles<span> (four </span>angles<span> altogether) always sum to a full </span>angle<span>(360°). In the figure above, </span>an angle<span> from each pair of </span>vertical angles<span> are adjacent</span>angles<span> and are </span>supplementary<span> (add to 180°). For example, in the figure above, m∠JQL + m∠LQK = 180°.</span>
I believe it would be the 4th one! :)
Let z be any number (like x would be)
if we set z equal to 2x-6y, then we get z = 2x-6y
The system
2x-6y = 8
2x-6 = 3
turns into this new system
z = 8
z = 3
but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
N= 1/8 I’m pretty sure I did that last year
