The sum of three consecutive even integers is –78. What are the integers?
Describe how you would use the strategy of writing an equation to solve the given problem.
hiya! i've been swamped on this question for a good bit now. i know what the answer is, but i'm not sure how to get there. Why are my integers n, n+2, and n+4? how do you find out those are the ones that you need to use? what's n? how does it work out the way it does? why and how do i get this answer? i just don't understand the process or the mind behind it and i need it to be broken down for me. Thank you!!
Step-by-step explanation:
(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)
Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.
We know that (n - 2) + n + (n + 2) = 78,
so 3n = 78, and n = 78/3 = 26.
Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

6m-6=9m+15 (Show work)
Answer:
Step-by-step explanation:
1. Subtract 9m from both sides.
6m-6-9m=9m+15-9m
-3m-6=15
2. Add 6 to both sides
-3m-6+6=15+6
-3m=21
3. Divide both sides by -3
-3m/3=21/-3
m= -7

Heather received grades of 80, 75, and 86 on 3
math 1 tests. What is lowest grade she can
receive on the next test if she wants her average
for the four test to be at least an 82?
Define your variable
Answer:
87
Step-by-step explanation:
We know Heather recieved grades of 80, 75 and 86.
Let's find her average on those 3 tests.
80 + 75 + 86 = 241 Since there are 3 tests we divide by 3.
241/3 = 80.3333 Is her aveerage on the first 3 tests.
She need to average 82 so we can write an equation with t being the score on her 4th test.
[tex]\frac{80 + 75 + 86 + t}{4} = 82[/tex]
[tex]\frac{241 + t}{4} = 82[/tex] Multiply each side by 4
([tex]\frac{241+t}{4}[/tex]) * 4 = 82 * 4 4 on the left will cancel
241 + t = 328 Subtract 241 from each side
241 - 241 + t = 328 - 241
t = 328 - 241
t = 87
Heather must get an 87 to have an average score of 82.

The club supplies 40 new balls for each player which cost $1 each. Each player pays $300 for the lessons. The club must pay each instructor $1,000 for conducting the lessons, and there must be at least 1 instructor for every 6 players. Which amount of players and instructors meets these requirements and still gives the club a net profit?
Answer:
4 players and 1 instructor
Step-by-step explanation:
If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160 200-160 = 40 The club will have $40 left.

Hello! Im stuck on this math question. The two triangles displayed are scaled copies of one another. the first question is "What is the scale factor?" the second question is "what is the value of x? "
Answer:
scale factor = 2.5
x = 10
Step-by-step explanation:
to find the scale factor, divide 10 by 4.
use the answer and divide it by 25 :)
________
10÷4=2.5
25÷2.5=10
The scale factor is 2.5 and the value of x will be 10.
What is a scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. The scale factor is the ratio of the scaled size to the original size.
Given that one triangle has the sides x and 4 and another has 25 and 10.
The scale factor will be calculated as below:-
Scale factor = 10 / 4
Scale factor = 2.5
Use the answer and divide it by 25. The value of x will be calculated as below:-
x = 25÷2.5
x = 10
Therefore, the scale factor is 2.5 and the value of x will be 10.

y= -2x+34 simplified
To be honest I am not sure
Good Luck Sorry if it is wrong.
Hey there!
[tex]Answer:\boxed{x=\frac{-1}{2}y+17}\boxed{y=-2x+34}[/tex]
[tex]Explanation:[/tex]
[tex]y=-2x+34[/tex]
flip the equation.
[tex]-2x+34=y[/tex] flip the equation.
Now add -34 to both sides of the equation.
[tex]-2x+34+-34=y+-34\\-2x=y-34[/tex] add -34 to both sides of the equation.
In our third/last step, we will divide both sides of the equation by -2.
[tex]\frac{-2x}{-2}=\frac{y-34}{-2}[/tex] divide both sides of the equation by -2.
[tex]x=\frac{-1}{2}y+17[/tex] The answer to your equation.
There is nothing to solve for y because the equation was equal to y.
Hope this helps!

Explain how to use a number line to show that opposite quantities combine to make zero.
did I do this correctly??
Yes your answer is correct.
Yes, you did it correctly.
We have two opposite quantities.
We have to show that opposite quantities combine to make zero.
What is a Vector quantity ? What are equal and opposite Vectors?Any quantity with both magnitude and direction is called vector quantity.
Two vectors are said to be equal and opposite if they have same magnitude and angle of 180 degrees between them.
According to the question -
Assume a number line and mark a number say 'x' after 0 and a number
'-x' before zero. These two numbers represent the quantities with same magnitude. And it can be easily seen that the angle between line from center point 'O' to 'x' and the line from 'O' to '- x' is 180 degrees. Hence, these two equal and opposite quantities which will give a resultant value of = + x + (- x) = + x - x = 0
And you also did it correctly ( You have taken 5 and -5).

Simplification of an expression is making it as simple as possible. The simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]
What are some basic properties of exponentiation?If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}\\\\^n\sqrt{a} = a^{1/n}\\(ab)^c = a^c \times b^c[/tex]
For the given case, the expression is simplified by using the given rules as:
[tex][3(2a)^{3/2}]^2 = 3^2 \times (2a)^{\dfrac{3}{2} \times 2} = 9 \times (2a)^3\\[/tex]
[tex][3(2a)^{3/2}]^2 = 9 \times 8 \times a^3 = 72a^3[/tex]
Thus, the simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

Answer:
Positive
Step-by-step explanation:

Remember, a number minus the negative of a number would be equal to that first number plus that second number but not negative. In other words:
a - (-b) = a + b
So:
[tex]\frac{2}{5}-(-\frac{5}{6})=\frac{2}{5}+\frac{5}{6}[/tex]
