The answer is:
1- A line of symmetry will connect a vertex and a midpoint of an opposite side.
2- It has 
-fold symmetry.
The explanation for this answer is shown below:
1- By definition, a line of symmetry is an imaginary line that divides a figure into two equal images or equal halves. If you connect a vertex and a midpoint of an opposite side of an heptagon by drawing a line, you will obtain two equal halves.
2- An heptagon has seven vertices, therefore, based on the information mentioned above, it has -fold symmetry.
After solving 
we get value of x = -20
Step-by-step explanation:
We need to solve the fractions and find value of x.
The given fraction is:
Solving:
So, After solving we get value of x = -20

24 can not be the total number of students in Mr. Castillo's class.
I'm assuming that your answer options are 20, 24, 25, and 30.
out of this set of numbers, 24 can not be divided by 5 (without getting a decimal)
Sizes = Small, Medium and Large, so they has 3 choices for size.
Crust = Thin or thick for each size, so they have 2 choices for crust.
Topping = Tomato or meatball for each one, so they have 2 choices for toppings.
The answer would be:
<span>Three choices for size, two choices for crust, and two choices for topping</span>
