Answer:

3500

Step-by-step explanation:

An average is just the total attendance numbers / the number of performances.

Let’s let the number of people in the third show be equal to x so we can write this as a formula, it’s easier to read. x is just "some number we don’t know"

The average is

Average=Total attendance/3

So

3000=(2580+2920+x)/3

So let’s multiply by that 3 on both sides, make x easier to find

Average*3=2580+2920+x ( * means multiplied)

The average is 3000

So

2580+2920+x=3000*3

2580+2920+x=9000

Then we subtract those other attendances to get x on its own.

x=9000-2580-2920

x=3500

I hope you have understood

The expression 9x2 - 5x - 7 has ___ terms and a constant of ___.
elena55 [62]
Answer: first option 3, - 7

Justification:

1) Given expression:9x² - 5x - 7

2) Each monomial is a term.

The monomials are each  combination of numbers and letters (coefficient, letters and exponents) separated of other monomials (terms) with a + or - operator.

3) Therefore, there are 3 terms which are:

9x²,
-5x, and
-7.

The polynomials with 3 terms are called monomials.

4) The monomial (term) withoud letter is the constant. In this case that is  -7.

If lines L and M are parallel, find x, y, and z. Explain your reasoning.
Katyanochek1 [597]

Answer:

The answer to your question is:

                                                     x = 43°, y = 137° and z= 43°

Step-by-step explanation:

-If lines L and M are parallel, that means that 43° and z are corresponding angles and they measure the same.

                                           z = 43°

- y and 43° are supplementary angles , so

                                          y + 43 = 180

                                          y = 180 - 43

                                          y = 137°

- x and z are vertical angles, so they measure the same

                                          x = z = 43°
