Hello. Would love to try and help, your screenshot is not showing up when I click on it though.
According to the characteristics of <em>ticket</em> sales and the resulting system of linear equations we find that 122 children bought each one a ticket on Sunday.
<h3>How many children went to the movie theatre?</h3>
In this question we have a <em>word</em> problem, whose information must be translated into <em>algebraic</em> expressions to find a solution. Let be x and y the number of children and adults that went to the movie theatre, respectively.
We need two <em>linear</em> equations, one for the number of people assisting to the theatre and another for the total sales:
x - 4 · y = 0 (1)
6.30 · x + 9.50 · y = 1063.20 (2)
By algebraic procedures the solution to this system is: x = 122.559, y = 30.639. Since the number of tickets sold are integers, then we truncate each result: x = 122, y = 30.
According to the characteristics of <em>ticket</em> sales and the resulting system of linear equations we find that 122 children bought each one a ticket on Sunday.

Solving for "K" , got it! :)
I'll make it easier to solve
(k)4+3-14=?
? = 0
4(k)-11 = 0
Take off the '0' and the addition symbol so we can add from 11 on your sides
4(k) - 11
+11 +11
---- ----
15k. 22
⬆ This would be your answer for k
4(k) = 11
÷4 ÷4
--- ----
1K ?
K = 11/4 (for fraction)
K = 2.75 (as a decimal)
Answer:
38 degrees
Step-by-step explanation:
By the Law of Cosines,
5² = 3² + 7² - 2(3)(7) cos A
5² - 3² - 7² = -2(3)(7) cos A
-33 = -42 cos A
cos A = 33/42
A = arccos(33/42), which is about 38 degrees.
