The requried, 40 more student tickets than adult tickets were sold.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let x be the number of adult tickets sold
Let y be the number of student tickets sold
We know that the total number of tickets sold is 230, so:
x + y = 230
We also know that the total amount collected from ticket sales is $995, so:
5.5x + 3.5y = 995
To solve for x and y, we can use the first equation to solve for one of the variables in terms of the other, and then substitute that expression into the second equation:
x + y = 230
y = 230 - x
5.5x + 3.5y = 995
5.5x + 3.5(230 - x) = 995
2x = 190
x = 95
So 95 adult tickets were sold. To find the number of student tickets sold, we can substitute this value of x back into the first equation:
x + y = 230
95 + y = 230
y = 135
Therefore, 135 student tickets were sold. To find how many more student tickets than adult tickets were sold, we can subtract the number of adult tickets from the number of student tickets:
135 - 95 = 40
Thus, 40 more student tickets than adult tickets were sold.

Cora and Daniel are both saving money each month. The total amount in their savings accounts is a function of the number of month
they have been saving. Each account is represented below.
Cora: y = 65x + 100, where y represents the total amount and x represents number of months
Daniel:
Answer:
Cora
Daniel
Daniel
Step-by-step explanation:
Forming equation for Daniel's saving from the plot:
Slope, m :
m = y2 - y1 / x2 - x1
m = (300 - 150) / (3 - 1)
m = 150 /2
m = 75
Intercept, c ; value of y when, x = 0
c = 75
Daniel's equation :
y = 75x + 75
Initial amout is described by intercept
Cora's intercept = 100
Daniel's intercept = 75
Rate is described by the slope
Daniel = 75
Cora = 65
So, Daniel is saving at a faster rate ; 75 to Cora's 65
Amount after 6 months :
After 6 months
y = 75*6 + 75 = $525
Cora:
y = 65x + 100
y = 65*6 + 100 = $490
Two numbers have a sum of 18, and 4 times the first number minus the second number is equal to 17. What is the smallest number?
Answer:
The smallest number is 7
Step-by-step explanation:
Using simultaneous equation;
x+y = 18.....(1)
4x-y = 17.....(2)
from equation (1)..
x+y = 18
y = 18-x...(3)
substitute y into equation (2)
4x-y = 17
4x-(18-x) = 17
4x-18+x = 17
4x+x = 17+18
5x = 35
x = 35÷5
x = 7
substitute x into equation (3)
y = 18-x
y = 18-7
y = 11
Therefore; x=7
y=11
11+7=18
(4×7)-11=17
the smallest number is 7

What is the rate of change of the linear function that has a graph that passes through (9,2) and (3,-1)?
=================================================
Explanation:
Your teacher wants you to find the slope
m = slope
m = (y2-y1)/(x2-x1)
m = (-1-2)/(3-9)
m = -3/(-6)
m = 1/2
----------------
Extra info:
We can think of the slope as
slope = rise/run
and furthermore,
rise = change in y = y2-y1run = change in x = x2-x1Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.

Find the area of the wrestling mat.
Answer:
804.25
Step-by-step explanation:
The area of a circle = pi(r)^2
Given the diameter, we can find the radius by dividing the diameter in half.
r=16
pi(16)^2 = 804.25
Answer:
803.84 OR 256 pi
Step-by-step explanation:
Ok!
Step 1:
The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)
R is radius. Remember, radius is half the diameter.
32/2=16.
Step 2:
Do 16^2.
You should get 256.
Step 3:
Multiply 256 by Pi. Pi is 3.14. You should get 803.84.
Step 4:
803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!

Un hotel tiene 120 habitaciones, entre dobles i individuales. Si la cuantidad de camas son de 195, cuantas habitaciones dobles hay? Y individuales?
Answer:
45 individuales y 75 dobles.
Step-by-step explanation:
Para saber esto, debemos plantearlo por medio de un sistema de ecuaciones. En este caso las incógnitas serían el tipo de habitación, es decir, una será la habitación doble, y la otra la individual.
X: habitaciones individuales
Y: habitaciones dobles
Sabiendo eso, sabemos que sumando ambos tipos de habitaciones, dan el total de 120, por tanto, la primera ecuación será:
x + y = 120 (1)
Para la segunda ecuación, sabemos que hay 195 camas en total, que deben distribuirse en los dos tipos de habitaciones, en una habitación doble van 2 camas, mientras que en una individual va 1, por tanto:
x + 2y = 195 (2)
Ahora que tenemos las dos ecuaciones, solo resta resolverlo por alguno de los métodos conocidos de sistema de ecuaciones. En este caso, como las ecuaciones son sencillas podemos usar el método de reducción.
En la siguiente foto, está el procedimiento.

A triangle has one angle measure of 55 degrees and a second angle measuring 53 degrees. What is the third missing angle measure? ______ degrees..
A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
Answer:
72 degrees
Step-by-step explanation:
First of all, you should know that each triangle equals to 180 degrees. So just add 55 + 53 which equals 108. Then you just subtract 108 from 180 (180-108) which equals to 72 degrees.
Therefore, the third missing angle measure is 72 degrees.
Hope this helps! :)
