I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER. Find the values of the variables. Then find the side lengths of the square.
X=_____
Y=_____
Answers
Step-by-step explanation:
I am not sure this is a square.
this could be a rectangle.
to be safe, I am following that path.
in a rectangle opposite sides are of equal length.
that means
y - 1 = 2y - 7
y = 2y - 6
0 = y - 6
y = 6
3x - 4 = 3y - 13
3x - 4 = 3×6 - 13
3x - 4 = 18 - 13 = 5
3x = 9
x = 3
as it turns out, it is a square, so we could have used every side expression to be equal with every other side expression, but better safe than sorry ...

Question 4 options:

2x−8=11
2(x−8)=11
2(x+8)=11
Answers
Answer:
2x+8=11
Step-by-step explanation:
The equation 2x + 8 = 11 would be the answer.
2 (coefficient) ----> it would multiply by the unknown value represented by the common variable "x".
Because in the given situation, it says twice (means 2 multiplied by a number or a number multiplied twice by itself) then multiplication would be the order of operation used between the 2 and x.
The "and" indicates the order of operation addition, as it is proven as the only given options for the answer all equal 11.
Therefore, proving that option A is the answer.

We have given that the total number of students is 4.
4 students are assigned to give presentations.
We have to find the arrangement of the 4 students.
What is the arrangement?
An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)
In a permutation, the order that we arrange the objects n is important.
4 students can be arranged by 4! ways.

Answer:
See below ~
Step-by-step explanation:
sin (A) = opposing side / hypotenuse
sin(A) = 5√29cos(A) = adjacent side / hypotenuse
cos(A) = 2/√29tan(A) = opposing side / adjacent side
tan(A) = 5/2 = 2.5Johanna, Elizabeth, and Dan are preparing a chemical solution for a research project. When
working alone, either Johanna or Elizabeth can prepare the solution in six minutes. Dan can
prepare the solution in four minutes if he works alone. How many minutes will it take the thre
of them to prepare the solution if they work together?
Answers
Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.
What is the together rate?It is the sum of each separate rate.
In this problem, the rates are given by:
Johanna's: 1/6.Elizabeth's: 1/6.Dan's: 1/4.Hence the together rate is given by:
[tex]\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}[/tex]
[tex]\frac{1}{x} = \frac{1}{3} + \frac{1}{4}[/tex]
[tex]\frac{1}{x} = \frac{4 + 3}{12}[/tex]
7x = 12
x = 12/7
x = 1.71.

Write an equation of the line that passes through the point (6,-9) with the given slope m= 3
Answers
Answer:
y = 3x - 27
Step-by-step explanation:
Since the slope is three, that is the only one that can be the answer.
answer: y = 3x - 27
explanation:
equation of a straight line: y = mx + c
( m is the slope and c the y- intercept )
here m = 3 , then y = 3x + c ← is the partial equation
to find c substitute (6, - 9) into the partial equation
-9 = 18 + c ⇒ c = -9 - 18 = - 27
y = 3x - 27 ← equation of line

Step-by-step explanation:

The required equation in slope-intercept form is y = - [tex]\frac{2}{3}[/tex]x + 4
What is an equation?An equation represents any two expressions or statements are equal that means they are having an equal to (=) sign in brtween them.
What is slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept is called slope-intercept form of the equation.
How to find the slope ?Slope of a line is the inclination of the straight line towards x axis.
If a straight line passes through two points (a , b) and (c , d), then slope(m) of the straight line can be calculated by the formula,[tex]m = \frac{d - b}{c-a}[/tex]
According to the problem, the straight line passes through (6 , 0) , (3 , 2) , (0, 4) , (-3 , 6).
Slope (m) = [tex]\frac{2-0}{3-6}[/tex] = - [tex]\frac{2}{3}[/tex]
How to write the equation in slope-intercept form?The equation can be written as
y = - [tex]\frac{2}{3}[/tex]x + b
Now , this line passes thorugh (0,4). So, (0,4) will satisfy the equation∴ putting (0,4) in the equation, we get,
y = 4
∴ The required equation is y = - [tex]\frac{2}{3}[/tex]x + 4.
For check we can satisfy the point ( -3 , 6) in the equation.- [tex]\frac{2}{3}[/tex](-3) + 4 = 6
CLearly, the point satisfies the equation.
So, the equation y = - [tex]\frac{2}{3}[/tex]x + 4 is correct

Given:
Mike is buying eight tickets for a concert.
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
To Find:
What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.
Solve:
Since we know that:
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
Hence we know that 5 + 3 = 8
Thus,
$74.45 = 5 tickets
Now for the 3 tickets we can do individual tickets which cost $17.25
$17.25 × 3 = 51.75
Then we add both together:
51.75 + 74.45 = $126.20
