Answer:

239 students and 153 non-students attended to the school production of "Our Town"

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets of the school production sold = 392

Student ticket cost = US$ 3

Non-students ticket cost = US$ 5

Total collected = US$ 1,482

2. How many students and how many non-students attended?

For answering the question we will use the following equation:

x = Number of students that attended the school production

392 - x = Number of non-students that attended the school production

3x + (392 - x) * 5 = 1,482

3x + 1,960 - 5x = 1,482

-2x = 1.482 - 1,960

-2x = - 478

x = -478/-2

x = 239 ⇒ 392 - 239 = 153

239 students and 153 non-students attended to the school production of "Our Town"

Help!!!!!!!!!!!!!!!!!!!!!!! please ty c:

Use the formula for the area of a triangle, and fill in the given information.
.. A = (1/2)*b*h
.. 36 in^2 = (1/2)*b*(9 in)
.. (72 in^2)/(9 in) = b . . . . . . . . multiply by 2, divide by 9 in
.. 8 in = b

The base is "none of the above", 8 inches.

_____
This question has a couple of problems:
.. 1) area is not measured in "inches"; it is measured in "square inches."
.. 2) ALL of the offered answer choices are INCORRECT.

Please help me! I will mark brainliest! I don't get polynomials and all that other stuff. So this question is really hard.

Answer:

Using sum and product method you can simplify the top as:

x^2-4x-5 = (x-5)(x+1) and x^2-5x+4 = (x-4)(x-1)

The x-4 and the x+1 cancel each other out and you will be left with

(x-5)/(x-1)
