I WILL GIVE BRAINILEST!!! Elvira is interested in collecting data about how many students use each of the tables during each lun

ch period. She has recorded some data on Post-It Notes to analyze later. Here are the notes she has recorded: ● Some students are sitting at the front table. (I got distracted by an incident in the back of the lunchroom,and forgot to record how many students.) ● Each of the students at the front table has been joined by a friend, doubling the number of students at the table. ● Four more students have just taken seats with the students at the front table. ● The students at the front table separated into three equal-sized groups. One group remained and all the other students left. ● As the lunch period ends, there are still 12 students seated at the front table. a) Create an equation and solve it to answer the above question. b) If the bullet points were in a different order, would the equation and answer still be the same? Use an example to help explain your answer.

A hole occurs when both numerator and denominator of  a rational function have the same factor.

<u>Step-by-step explanation:</u>

While graphing rational function, it has to be converted into the lowest terms by factoring the numerator and denominator. If the numerator and denominator has the same factor, a hole is said to have occurred and to solve the rational function, you have to set the common factor to zero.

After you set it to zero and solve, you obtain the x value which can be then used to find out the value of y.

12x15y=4140; x+y= ? <br> solve.
Semenov [28]

Answer: The number of $12 tickets and $15 sold are 120 and 180 respectively.

Step-by-step explanation:

The given equation is:

12x + 15y = 4140             .....(1)

Where,

x stands for $12 tickets and y stands for $15 tickets

According to the question:

x + y = 300           ....(2)

Now solving equation 1 and 2.

From equation 2:

x = 300 - y

Now putting this expression in equation 1.

12x + 15y = 4140

12(300 - y) + 15y = 4140

3600 - 12y + 15y = 4140

3600 + 3y = 4140

3y = 4140 - 3600

3y = 540

y = 180

And,

x = 300 - y = 300 - 180 = 120

The number of $12 tickets sold = x = 120

The number of $15 tickets sold = y = 180

Thus, the number of $12 tickets and $15 sold are 120 and 180 respectively.
