Get rid of the z first.
3x + y = 2z
Then the y.
3x = 2z - y
Then divide both sides by 3 to isolate x.
x = 2/3z - 1/3y
The x value is ( z - 2 ) / 3z.
Given,
3x+y/z=2
We need to solve for x.
We have,
3x+y/z=2
Subtracting y/z on both sides.
we get,
3x + y/z - y/z = 2 - y/z
3x = 2 - y/x
Dividing 3 into both sides.
we get,
x = ( 2 - y/z ) / 3
We can simplify further.
x = [( z - 2 ) / z ] / 3
x = ( z - 2 ) / 3z
Thus the x value is ( z - 2 ) / 3z.

The length of a rectangle is 4 inches more than its width. The area of the rectangle is equal to 4 inches less than 5 times the perimeter. Find the length and width of the rectangle.
Answers
Let the width of the rectsngle (b) be x
and the length of the rectangle (l) =x+4
Area of the rectangle (A)=?
Perimeter of the rectangle (P)=?
Now,
P= 2 (l+b)
= 2 (x+4+x)
= 2 (2x+4)
= 4x+8
And,
A= l×b
= x(x+4)
= x^2+4x
According to the question,
A=5P-4
or, x^2+4x =5 (4x+8)-4
or, x^2 +4x =20x+40-4
or, x^2 = 20x-4x+36
or, x^2 = 16x+36
or, x^2-16x-36 = 0
or, x^2-(18-2)x-36 = 0
or, x^2-18x+2x-36 = 0
or, x (x-18)+2 (x-18) = 0
or, (x-18) (x+2) = 0
Either, Or,
x-18 = 0 x+2 = 0
so, x = 18 so, x = -2
Taking the value of x = 18 ( Because the length is always positive)
Length = x+4 = 18+4 = 22 cm
Width = x = 18 cm

Final answer: 13
Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers in the data set. In this case, you would add
10 + 11 + 12 + 13 + 14 + 14 + 14 + 14 +15
Step 2: Divide the sum by the number of digits you added.
In this case you would divide 117 by 9 and you will get a quotient of 13

An acrobat of mass m slides down a vertical rope of height h. For the first three quarter of her descent she grips the rope with her hands and legs so as to produce a fictional force equal to five-ninth of her weight.she then tighten her grip so that she comes to rest at the bottom of the rope. Sketch a (t .v) graph to illustrate her descent
Answers
The acrobat's descent on a time versus velocity graph would show an initial linear increase in velocity due to gravity minus frictional force, followed by a sharp negative slope as she comes to a stop at the bottom.
The acrobat's descent can be analyzed by plotting a time (t) versus velocity (v) graph. Initially, the acrobat experiences a frictional force equal to five-ninths of her weight, which creates constant deceleration. For the first three quarters of the descent, her velocity will increase linearly (assuming constant deceleration) until she tightens her grip, which will cause a sharp decrease in velocity until she comes to a complete stop at the bottom. The graph would show a slope that decreases in magnitude over time and then drops to zero when the acrobat comes to rest.
Example Graph Description:The graph starts at the origin (0,0), indicating that the descent starts from rest.As time progresses, the velocity increases linearly due to the effect of gravity partially opposed by frictional force.Before reaching the bottom, the acrobat applies enough force to stop, leading to a sharp negative slope on the graph that touches the t-axis, indicating a stop.At the beach 29% of people have red towels and 18% have white towels if the rest have blue ,what percentage of the people at the beach have blue towels
Answers
✯1 - (0.29 + 0.18) = 0.53

Answer:
x = 50 .
Step-by-step explanation:
Given : Mean of 5,10,15 and x is 20.
To find : What is the x.
Solution : We have given Mean of 5, 10 , 15 and x is 20.
Mean = 20 .
Mean = [tex]\frac{sum\ of \ data}{Number\ of \ data}[/tex].
Mean = [tex]\frac{5+10+15 +x}{4}[/tex].
20 = [tex]\frac{30 +x}{4}[/tex].
On multiplying both sides by 4
20 * 4 = 30 + x .
80 = 30 + x .
On subtracting both sides by 30.
50 = x
Therefore, x = 50 .

The weight of an African elephant is 6x10^6 grams; the weight of a tiger is 3x10^5 grams. How many times heavier is the elephant than the tiger?
Answers
elephant= x times tiger
6 times 10^6=x times 3 times 10^5
divide both sides by (3 times 10^5)
remember that (x^m)/(x^n)=x^(m-n)
so
(6 times 10^6)/(3 times 10^5)=x
(6/3) times (10^6)/(10^5)=x
2 times 10^1=x
2 times 10=x
that would be 2 times 10^1 or 20 times

Answers
Rational exponent is an exponent that is fractional in form. Let us dissect this one by one.
An n root means that the number or the variable has a power raised 1 / n. For example, if we have a square root of x, this means that x^(1/2).
So in this case since this is cube root, therefore our total variable is raised to the power of 1 / 3.
Since it is also raised to the power of 5, therefore the total power is 5 / 3. This makes the variable in the form:
(x^4)^(5 / 3)
To simplify this further, our variable x is raised also to the power of 4, therefore we multiply the powers. Which simplify this further into:
x^20 / 3

A cell phone company wants to place a new cell tower so that it is the same distance from the centers of the three towns. How can the company find where to place the tower? Explain.
Answers
The company can find where to place the tower by determining the point of concurrency of these three (3) towns.
What is a triangle?A triangle refers to a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.
What is a point of concurrency?A point of concurrency can be defined as a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when at least three (3) lines intersect at a single point.
Based on geometry, the point (circumcenter) that is equidistant from the vertices of the triangular tower would be equal in distance from each of the centers of these three (3) towns.Generally, the circumcenter of a triangle can easily be determined by constructing the point of concurrency of the perpendicular bisectors of a triangle.In conclusion, the company can find where to place the tower by determining the point of concurrency of these three (3) towns, so that they all have the same distance from the centers.

Answer:
For the tower to be the same distance from each of the centers, the company must find the point that is equidistant from the vertices of the triangle. This is the circumcenter of the triangle and can be found by constructing the point of concurrency of the perpendicular bisectors of the triangle.
The tower needs to be equidistant from the vertices of the triangle.
The tower should be placed at the circumcenter of the triangle.
To find the circumcenter, find the intersection point of the three perpendicular bisectors of the triangle.
