Step-by-step explanation:
this is an exercise to take the logical definition of an operation and apply it.
we have first a triangle operation that simply stands for the sum of the 3 included values divided by 3.
in other words, FYI, it creates the mean value of 3 given numbers.
so, we need to calculate
mean value (7, 4, 4) + mean value (8, 2, 11).
(7 + 4 + 4)/3 + (8 + 2 + 11)/3 = 15/3 + 21/3 = 36/3 = 12
the second calculation is based on a table defining a new operation Delta :
2 Delta 2 = 20
2 Delta 5 = 5
2 Delta 3 = 5
5 Delta 2 = 3
5 Delta 5 = 10
5 Delta 3 = 23
3 Delta 2 = 3
3 Delta 5 = 2
3 Delta 3 = 50
so, now we need to use this to calculate
(5 Delta 2) Delta (2 Delta 3)
3 Delta 5
2
the result is 2.

For problems 12-14, describe the similarities and differences between the expressions.
12. -3 and -(3)

14. -2(4) and -(2•4)
The similarities between the expressions in all the three problems is that after opening brackets both of the expressions are the same.
How to check if two expressions are similar?Two expressions are similar if their values after solving are equal.
12. -3 and -(3)
Here, when we open the bracket for -(3), we obtain -3 which is the same as the first expression.
13. -1(7) and -(7)
Solving for the first expression, we get -1×7 = -7 and
-(7) = -7.
We can see that both expressions are similar.
14. -2(4) and -(2•4)
Solving -2(4), we get -2×4 = -8
And, -(2·4) = -(8) which is the same as -8

Use the diagram to find the angle measures that satisfy each case. Find the measures of all 4 angles if m<2-m<1=30 degrees
The measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105
How to use the diagram to find the angle measures that satisfy each case?The diagram that completes the question is added as an attachment
From the diagram, we have
<1 + <2 = 180 degrees --- supplementary angles
Given that
<2 - <1 = 30 degrees
Add the above equations
So, we have
2<2 = 210
Divide both sides by 2
<2 = 105
Substitute <2 = 105 in <2 - <1 = 30
So, we have
105 - <1 = 30
Evaluate
<1 = 85
Also, we have
<3 = <1
<4 = <2
This means that
<3 = 85
<4 = 105
Hence, the measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

Find the horizontal asymptotes by comparing the degrees of the numerator and denominator.
Vertical Asymptotes:
x=−2,2Horizontal Asymptotes:
y=1
No Oblique Asymptotes
Full Explanation
The line x=L is a vertical asymptote of the function [tex] y=\frac{x^{2} + 3 x + 6}{x^{2} - 4}[/tex] if the limit of the function (one-sided) at this point is infinite.
In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.
So, find the points where the denominator equals 0 and check them.
x=−2, check: [tex] \lim_{x \to -2^+}\left(\frac{x^{2} + 3 x + 6}{x^{2} - 4}\right)=-\infty [/tex]
Since the limit is infinite, then x=−2 is a vertical asymptote.
x=2, check: [tex]\lim_{x \to 2^+}\left(\frac{x^{2} + 3 x + 6}{x^{2} - 4}\right)=\infty[/tex]
Since the limit is infinite, then x=2 is a vertical asymptote.
Vertical asymptotes: x=−2; x=2
Two planes, which are 2670 miles apart, fly toward each other. Their speeds differ by 90mph. If they pass each other in 3 hours, what is the speed of each?
400mph and 490mph
The speed of the fast plane is 490 mph while the speed of the slow plane is 400 mph
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the speed of the fast plane and y represent the speed of the slow plane.
Their speeds differ by 90mph, hence:
x - y = 90 (1)
The planes meet after 3 hours, hence:
3x + 3y = 2670 (2)
From both equations:

How many boys are there in an introductory geology course if 392 students are enrolled and there are five boys to every three girls?
Answer
How to enter your answer (opens in new window)
The number of girls is 147 and the number of boys is 245 in the introductory geology course
Students enrolled in the introductory geology course = 392 students
The ratio of boys to girls in the course = 5:3
Let the number of girls in the course be x, then the number of boys will be 392-x
Formulating the equation we get:
Number of boys/Number of girls = Ratio of boys/Ratio of girls
= 392-x/x = 5/3
= (392-x)*3 = 5x
= 1176-3x = 5x
=1176 = 8x
x = 147

Existence of an Inverse
There are two numbers that f takes to 4, f(2) = 4 and f(-2) = 4. If f had an inverse, then the fact that f(2) = 4 would imply that the inverse of f takes 4 back to 2. On the other hand, since f(-2) = 4, the inverse of f would have to take 4 to -2.
A minor league baseball park has 7000 seats. Box seats cost $6, grandstand seats cost $4, and bleacher seats
cost $2. When all seats are sold, the revenue is $26,400. If the number of box seats is one-third the number of
bleacher seats, how many seats of each type are there? Give a complete sentence explaining what your answers
mean.
Taking into account the definition of a system of linear equations, the number of box seats is 400, the number of bleacher seats is 1200 and the number of grandstand is 5400.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, the values of the unknowns must give the solution proposed in both equations.
Amount of seats of each typeIn this case, a system of linear equations must be proposed taking into account that:
"B" is the number of box seats."G" is the numer of grandstand seats."BL" is the number of bleacher seats.You know that:
A minor league baseball park has 7000 seats.Box seats cost $6, grandstand seats cost $4, and bleacher seats cost $2. When all seats are sold, the revenue is $26,400. The number of box seats is one-third the number of bleacher seats,So, the system of equations to be solved is
Equation 1: B + G + BL= 7000
Equation 2: 6B + 4G + 2BL= 26400
Equation 3: B= 1/3BL
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, replacing equation 3 in equation 1 and isolating the variable G, you get:
1/3BL + G + BL= 7000
4/3BL + G= 7000
G= 7000 - 4/3BL
Substituting this expression and equation 3 into equation 2 you get
6×1/3BL + 4×(7000 - 4/3BL) + 2BL= 26400
Solving:
2BL + 4×7000 - 4×4/3BL + 2 BL= 26400
2BL + 28000 - 16/3BL + 2 BL= 26400
2BL - 16/3BL + 2 BL= 26400 - 28000
-4/3BL= -1600
BL= (-1600)÷ (-4/3)
BL= 1200
Remembering that B= 1/3BL and G= 7000 - 4/3BL and replacing the value of BL you get:
B= 1/3BL= 1/3×1200 → B= 400
G= 7000 - 4/3BL= 7000 - 4/3×1200 → G= 5400
In summary, the number of box seats is 400, the number of bleacher seats is 1200 and the number of grandstand is 5400.

Each month, Braxton uses an average of 8 ounces of lotion. Calculate Braxton's total monthly savings if he purchases the brand that has the lowest price per ounce versus the highest price per ounce.
Brand A: 24 ounces for $3.30
Brand B: 40 ounces for $4.60
a $0.18
b $0.75
с $1.30
d $1.50
Option a: Broxton have a monthly savings of $0.18 if he purchases the brand that has the lowest price per ounce versus the highest price
Given,
Braxton’s average monthly usage of lotion = 8 ounces
The amount of two different brands of lotion are given:
Brand A: 24 ounces for $3.30
Brand B: 40 ounces for $4.60
We have to find the monthly savings of Braxton if he purchases the brand that has the lowest price per ounce versus the highest price:
We have to calculate amount for one ounce for the two brands given:
Brand A:
24 ounces for $3.30
Amount for one ounce = 3.30/24
Amount for one ounce = $0.1375
Brand B:
40 ounces for $4.60
Amount for one ounce = 4.60/40
Amount for one ounce = $0.115
Now, we have to calculate the amount for 8 ounces.
Brand A:
8 x 0.1375 = 1.1
$1.1 for 8 ounces of Brand A lotion.
Brand B:
8 x 0.115 = 0.92
$0.92 for 8 ounces of Brand B lotion.
Now, we have to calculate the savings:
Brand A – Brand B
1.1 – 0.92 = 0.18
That is, Broxton have a monthly savings of $0.18 if he purchases the brand that has the lowest price per ounce versus the highest price.

Answer:
5x = 8(x - 3)
5x = 8x - 24 → Expand the brackets
-3x = -24 → Collect like terms ,which simply means that you'll transfer 8x to the other side , which will make it -8x
x = 8 → Divide both sides by the coefficient of x (3) : minus cancels minus; then 24 ÷ 3 = 8.
