choli [55]

Answer:

The  number of children's tickets sold was 31 and the number of  adult tickets sold was 2

Step-by-step explanation:

Let

x ---> the number of children's tickets sold

y ---> the number of  adult tickets sold

we know that

the theater sold 33 tickets

so

x+y=33 -----> equation A

the theater made a total of $158.50

so

4.50x+9.50y=158.50 ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (31,2)

see the attached figure

therefore

The  number of children's tickets sold was 31 and the number of  adult tickets sold was 2

How do u convert a fraction into a decimal
lesya692 [45]
You have to divide the numerator (top number) by the denominator (bottom number). For example, 1/2 is 0.5
However, some end up as never-ending decimals, like 1/3, which converts to 0.333 repeating.

A line has a slope of –3 and a y-intercept of (0, –1). What is the equation of the line that is parallel to the given line and p
givi [52]
Well, the first line has a slope of -3, and runs through 0, -1.

a line parallel to that one, will have the same exact slope of -3.

now, we know about this other parallel line that it runs through -3,1, and of course, since is parallel, it has a slope of -3

\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1\\&#10;&&(~ -3 &,& 1~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies -3&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-1=-3[x-(-3)]&#10;\\\\\\&#10;y-1=-3(x+3)&#10;\implies &#10;y-1=-3x-9\implies y=-3x-8
