A small art museum charges $5 for an adult ticket and $3 for a student
Shkiper50 [21]

There were 37 student tickets and 52 adult tickets

Step-by-step explanation:

Let x be the number of student tickets and y be the adult tickets

Then

According to given statement that total 89 tickets were sold

x+y=89     Eqn 1

And

$5 for an adult ticket and $3 for student ticket ,and total cost $371

3x+5y=371    Eqn 2

From eqn 1

x=89-y

Putting in eqn 2

3(89-y)+5y=371\\267-3y+5y=371\\267+2y=371

Subtracting 267 from both sides

267+2y-267=371-267\\2y=104

Dividing both sides by 2

\frac{2y}{2}=\frac{104}{2}\\y=52

Putting y=52 in eqn 1

x+52=89\\x=89-52\\x=37

Hence,

There were 37 student tickets and 52 adult tickets

Again another Pythagorean Theorem i need help on, please and thank you
vodka [1.7K]

     You commented that part of the instruction included "If the theorem cannot be applied, explain the reason."

     The theorem cannot be applied. Since this is not a right triangle, we cannot solve using the Pythagorean Theorem unless we are given a height. If we have the height of this triangle, then we can break it into two different right triangles and solve.

What is a right triangle? A right triangle is a triangle that has an angle measurement of 90 degrees.

       In summary, this is an isosceles triangle and the Pythagorean Theorem only applies to right triangles.
