Answer: [tex]x = \frac{mn(q - p)}{n-m}\\\\[/tex]
================================================
Work Shown:
Part 1
[tex]\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\[/tex]
Part 2
[tex]\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\[/tex]
-------------------------------
Explanations:
There are quite a bit of steps. I decided to break things into two parts.The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero. If the formulas don't properly display, then you might have to refresh the page.-3x+6y=15 and -3x-2y=-1*

Answer:
The Circumference of the circle = C = 24π mm
Hence, option C is true.
Step-by-step explanation:
Given
Radius r = 12mm
To Determine
Circumference of circle C = ?
Using the formula to determine the Circumference of the circle
C = 2πr
substituting r = 12mm in the equation
C = 2π(12)
C = 24π mm
Therefore, the Circumference of the circle = C = 24π mm
Hence, option C is true.
show me a Graph x=−4.
Answer:
The graph of line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
Step-by-step explanation:
Given the line
x=−4
The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.
As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
The graph of the line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,

help me answer this trignometry question. the final answer is actually is 18.3 .but i get something else.
Answer:
y ≈ 18.3
Step-by-step explanation:
Using the sine ratio in the right triangle
sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{y}[/tex] ( multiply both sides by y )
y × sin41° = 12 ( divide both sides by sin41° )
y = [tex]\frac{12}{sin41}[/tex] ≈ 18.3 ( to 1 dec. place )

Question 5 (5 points)
Answer:
Option 1 is correct i.e.
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]
Step-by-step explanation:
We need to simplify the expression: [tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2[/tex]
We know that: [tex](a^m)^n= a^{m*n}[/tex] and [tex]a^0=1[/tex]
We would use these exponent laws to solve our question.
First we will apply [tex]a^0=1[/tex]
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2\\=(\frac{2^3\:\textbf{.}\:1}{5})^2\\[/tex]
Now, we will apply [tex](a^m)^n= a^{m*n}[/tex]
[tex]=\frac{(2^3)^2\:\textbf{.}\:1^2}{5^2}\\=\frac{2^6\:\textbf{.}\:1}{5^2}\\=\frac{64}{25}[/tex]
So, the result is: [tex]\frac{64}{25}[/tex]
Therefore, Option 1 is correct i.e.
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]

Answer:
y=-4x+5
Step-by-step explanation:
Let us first find the slope.
Given the points, (0,5) and (1,1) The slope of the line is (5-1)/(0-1)=
4/-1=
-4
The line also intercects the y axis at (0,5) Therefore, the b intercept would be 5
The final equation would be,
y=-4x+5
I hope this helps! :)
Answer:
y = -4x + 5

Lynn has a box of crayons.
4/9 of the crayons are blue
65% of the remaining crayons are red.
The other 14 crayons are yellow.
How many crayons are in the box altogether?
Answer:
There are 72 crayons in the box
Step-by-step explanation:
Fractions
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:
[tex]1-\frac{4}{9}=\frac{5}{9}[/tex]
From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:
[tex]\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}[/tex]
Thus, the portion of yellow crayons is:
[tex]\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}[/tex]
This fraction of x crayons is equal to 14, thus:
[tex]\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}[/tex]
x = 72
There are 72 crayons in the box
