Answer:
35 hotdogs and 52 sodas sold.
Step-by-step explanation:
x = the number of hotdogs sold, x>0
y = the number of sodas sold, y>0
At the end of the night you made a total of $78.50:
1.50x + 0.50y = 78.50
You sold a total of 87 hotdogs and sodas combined:
x + y = 87
We have the following system of equations:
1.50x + 0.50y = 78.50
x + y = 87
To put this in simpler form, you combine like terms:
-4j - 1 - 4j + 6
-8j - 1 + 6
final answer: -8j + 5
Keep in mind that a lot of teachers teach math sifferently, so the way I was taught could be different from the way you earned. This was one of the simplest ways to do it.

Step-by-step explanation:
We know that
∠1=∠5------------> by corresponding angles are congruent
so
∠5=58°
and
∠5+∠7=180----------> by supplementary angles
so
∠7=180-∠5--------> 180-58--------> 122°
the answer is ∠7=122°
