According to the given question.
Registration fee for the dance class = $15
Amount of money charges for each dance class = $24
Amount of money paid for c number of classes = $687
⇒ [tex]687 = 24c + 15[/tex]
Solve the above linear equation in one variable for c.
[tex]687 = 24c + 15[/tex]
⇒ [tex]687 - 15 = 24c[/tex]
⇒ [tex]672 = 24c[/tex]
⇒ [tex]c = \frac{672}{24}[/tex]
⇒ [tex]c = 28[/tex]
Hence, the number of classes is 28.

What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Jansen family has 2 1/2 gallons of milk. Each of the 3 family members drinks 1 1/2 cups of milk a day.
1 gallon = 16 cups
2[tex]\frac{1}{2}[/tex] gallons = 2[tex]\frac{1}{2}[/tex] x 16 = 5/2 x 16 = 5 x 8 = 40 cups
Now -
Total milk consumed in 1 day = 3 x 3/2 cups = 9/2 cups = 4.5 cups.
In 8 days, the amount of milk consumed will be = 4.5 x 8 = 36 gallons.
Remaining amount = 40 - 36 = 4 gallons.
Therefore, the amount of milk remaining is equivalent to 4 gallons.

Step-by-step explanation:
A triangle is 180 degrees, the top part is 88.
180 - 88 = 92
92/2 = 46.
Answer: 44°
Explanation:-
Method 1:-
We know that the sum of the measurements of two interior angles is equal to the measurement of the exterior angle.
i.e.,
y + y = 88°
→ 2y = 88°
→ y = 88°/2
→ y = 44° (D)
Method 2:-
The adjacent angel of the angle of measurement 88° is 92°.
We know,
Sum of interior angles of a triangle = 180°
According to the Question:-
y + y + 92° = 180°
→ 2y = 180° - 92°
→ 2y = 88°
→ y = 44° (D)

what is the value of x ?
Step-by-step explanation:
2(2x - 6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26
4x + 2x -12 + 6 = 26
6x - 6 = 26
6x = 26 + 6
6x = 32
x =32/6
x = 5.3333
Answer:
Step-by-step explanation:
2(2x -6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26
6x - 6 = 26
6x = 32
x = 32/6= 16/3
