The solution is, The value of x is 6.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have.
given that,
Figure VWYX is a kite.
Sides V W and W Y are congruent, and sides V X and Y X are congruent.
Angles V and Y are right angles.
Angle W is (18 x minus 2) degrees and angle X is (12 x + 2) degrees.
The total of angles in any quadrilateral is 360°.
Angles V and Y are 90° each,
so the total of W and X must be 180°.
we have,
(18x -2) +(12x +2) = 180
30x = 180
x = 180/30
= 6
The value of x is 6.

How many solutions does the system of equations below have?
x − 4y = 6
2x − 8y = 12
Answer:
One solution
Step-by-step explanation:
x - 4y = 6
-4y = 6 - x
-4y/-4 = 6/-4 -x/-4
y = -6/4 + -x/4
2x − 8y = 12
-8y = 12 - 2x
-8y/-8 = 12/-8 - 2x/-8
y = -12/8 + 2x/8
Graph "y = -6/4 + -x/4" and "y = -12/8 + 2x/8" to find how many solutions these lines have.
As shown below, it has only one solution.
a cylindrical can needs to have a volume of 6 cubic inches a label is to go around the side of the can. The function S(r)=12/r gives the area of the label in square inches where r is the radius of the can in inches
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attachment.
Cylinder volume V= 6 Cubes - inch
The Formula:
[tex]\to V=\pi r^2 h= 6[/tex]
The (r and h ) is the radius and height of the cylinder and [tex]s(r)= \frac{12}{r}[/tex]represent the region of the mark in this r and h, and that is why as can's radius gets bigger and larger, the label area gets closer to 0.

Part of a regular polygon is shown below. Each interior angle is 150°. (4
150°
Diagram not
accurately drawn
Calculate the number of sides of the polygon.
Answer:
12 side polygon
Step-by-step explanation:
Interior angle of n side regular polygon: = ((n-2)x180)/n
((n-2)x180)/n = 150
(n-2)x180 = 150n
180n - 360 = 150n
30n = 360
n = 12
check: (12-2)x180/12 = 150
Answer:
The polygon has 12 sides (a dodecagon).
Step-by-step explanation:
Angles in a Regular Polygon
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that each angle (in a regular polygon) measures
[tex]\displaystyle \frac{180(n-2)}{n}[/tex]
We are given the interior angle of 150°, thus:
[tex]\displaystyle \frac{180(n-2)}{n}=150[/tex]
Multiplying by n:
[tex]\displaystyle 180(n-2)=150n[/tex]
Operating
[tex]\displaystyle 180n-360=150n[/tex]
Rearranging and simplifying:
[tex]\displaystyle 180n-150n=360[/tex]
[tex]\displaystyle 30n=360[/tex]
[tex]n=360/30=12[/tex]
n = 12
The polygon has 12 sides (a dodecagon).
A power function with form y = ax passes through the points (2,
5
and 3,
81
Find the constants a
and pa=
p=
Answer: a = 47.3;
p = 0.65
Step-by-step explanation: A power function is of the form [tex]y=ax^{p}[/tex] and passes through points (2,5) and (3,81), i.e.:
[tex]5=a.2^{p}[/tex]
[tex]81=a.3^{p}[/tex]
To determine the two unknows, solve the system of equations:
[tex]log5=log(a.2^{p})[/tex]
[tex]log81=log(a.3^{p})[/tex]
Using multiplication and power rules:
[tex]log5=loga+plog2[/tex]
[tex]log81=loga+plog3[/tex]
Giving values to constants:
0.7=loga+0.3p
2=loga+0.5p
This system of equations can be solved by subtracting each other:
[tex]-1.3=-0.2p[/tex]
p = 0.65
Substituting p into one of the equations above:
[tex]loga+0.5(0.65)=2[/tex]
[tex]loga=1.675[/tex]
[tex]a=10^{1.675}[/tex]
a = 47.3
The constants a and p of the power function which passes through points (2,5) and (3,81) are 47.3 and 0.65, respectively.

Answer:
Cannot prove as congruent
Step-by-step explanation:
AAA cannot be used to prove whether a triangle is congruent. Only SSS, SAS, ASA, and AAS can be used.
The verticles of triangle A are (-1,3) B (7,9) and C (15,-3) Find the coordinates of the intersection of the medians.
please help
Step-by-step explanation:
Coordinates of A≡(−1,3)
Coordinates of B≡(7,9)
Coordinates of C≡(15,-3)
The median through the vertex C will meet at the mid point of AB.
Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)
Now,
Length of median through vertex C= Distance between (15,-3) and (3,6)
Therefore,
Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit
Hence the length of median through the vertx C is 15 units.

may run 6 miles in 54 minutes how long will it take her to run 10 miles
Answer:
It would take her 90 minutes to run 10 miles.
Step-by-step explanation:
First you should divide 54 by 6 and you'll get 9. So it takes her 9 minutes to run 10 miles (which is physically impossible). You multiply 9 times 10 and get 90.

----------------------------------------------
Explanation:
There are a lot of steps, so I broke things up into 3 sections or parts. The idea I'm applying is if the denominator is of the form [tex]a+\sqrt{b}[/tex], then multiplying top and bottom by [tex]a-\sqrt{b}[/tex] will rationalize the denominator. This is due to the difference of squares rule (step 3 of part 1). The following step shows squaring a square root has the two cancel out.
From that point, I simplified each square root and factored to cancel out a pair of '4's.
To expand out [tex](2-\sqrt{8})(4-\sqrt{12})[/tex], we can use either the FOIL method, the box method, or the distribution property. I used the distribution property.

In the first week of January, there are 49 dogs and 28 cats in an animal shelter. Throughout the month, the ratio of dogs to cats remains the same. In the last week of January, there are 20 cats in the shelter. How many dogs are there?
Answer:
35 dogs
Step-by-step explanation:
Given
[tex]49\ dogs: 28\ cats[/tex]
Required
Determine the number of dogs for 20 cats
Represent the required number of dogs as a ratio of number of cats
[tex]x : 20\ cats[/tex]
So, we have:
[tex]49\ dogs: 28\ cats[/tex]
[tex]x : 20\ cats[/tex]
Since, the ratio is the same throughout, we have:
[tex]x : 20\ cats[/tex] = [tex]49\ dogs: 28\ cats[/tex]
Convert ratio to fraction
[tex]\frac{x}{20} = \frac{49}{28}[/tex]
[tex]\frac{x}{20} = \frac{7}{4}[/tex]
Multiply through by 20
[tex]x = \frac{7}{4} * 20[/tex]
[tex]x = 7 * 5[/tex]
[tex]x = 35[/tex]

Joe and Susan are both 40 years old and hope to have enough money saved to retire by the time they're 65. They deposit $6,000 each

$249,875
$286,363
Answer:
Formula: Future value of annuity
In 20 years: $249,875
Total Interest: $99,875
Step-by-step explanation:
Use the formula for future value:
FV =
P = $6,000
r = 0.04
n = 1
t = 25
FV =
FV = $249,875
To find the total interest earned, first find the total value of the deposit payments:
$6,000 annual payments for 25 years = 6,000 • 25
= $150,000
(I copied that explanation from somewhere else so its a little messed up. I just couldn't explain it properly. Hope this helps!)
Account balance In 20 years is $249,875 and total interest earned is $99,875.
What is the future value?The FV formula assumes a constant rate of growth and a single up-front payment left untouched for the duration of the investment. The FV calculation can be done one of two ways, depending on the type of interest being earned.
We have,
P = $6,000
r = 0.04
n = 1
t = 25
We know the formula for future value
FV= PV [tex](1 + r)^{n}[/tex].
where:
P=Investment amount
R=Interest rate
T=Number of years
According to the question
FV=$6,000×(1+0.04
FV = $249,875
To find the total interest earned, first find the total value of the deposit payments:$6,000 annual payments for 25 years = 6,000 × 25= $150,000
Total interest earned = FV - annually payment for 25 year = $249,875 - $150,000 = $99,875

Step-by-step explanation:
Remark
We are going to go through an extensive discussion of the value of x. The value for y is found exactly the same way.
Top diagram.
The top diagram establishes the fact that if any two points are on the major arc of the circle whose center is 0, then the vertex of the of the two angles so formed are equal. The end points of these two angles must be established by the endpoints of the chord A and B.
Put in much simpler language.
<ACB = <AC'B
The end points of the angles are A and B of the Chord AB.
The Vertex of the angles are both on the major arc of the circle. These two are C and C'
Bottom Diagram
The idea here is to find the value of C. If we do that, then we know what x is in the diagram you provided.
Draw diameter COA Construction
< CAB = 90 Any vertex (C) on circumference with diameter endpoints (A & C) = 90
<CAT_1 = 90 A diameter always meets a tangent at 90o
<BAT_1 = 37 Given
<CAB = 90-37 <CAB and <BAT_1 are complementary
<ACB = 37 A right triangle's acute angles are complementary.
<ACB = x = 37o See top diagram
