Answer:
Step-by-step explanation:
Let
t -----> the number of tickets
y ----> the total amount raised
we know that
The linear equations that represent this situation are
<u><em>One Class</em></u>
-----> equation A
<u><em>Other Class</em></u>
-----> equation B
Solve the system of equations
Equate equation A and equation B and solve for t
Both are supplementary angles.

Answer:
x=59
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 180 degrees. That means that (x+12)+(x)+(x-9)=180 degrees in total. If we combine the like terms (combine the xs and regular constant values), the xs add up to 3x (x+x+x) and the regular constants add up to 3 (12+-9=3). If we rewrite this in a more simplified form, we get 3x+3=180. Subtract 3 on both sides to get 3x=177 because we want to isolate x. 3x=177 divide 3 on both sides and we get 59. x=59
