Step-by-step explanation:
Well, there's a formula: to find the measure of any section, you should multiple every section to its ending after the crossing, and then make a proportion.
So, 9(n+7) = 18(n+1)
9n+63 = 18n+18

What is 3 1/4=1/2+w what is w
Answer:
2 3/4.
Step-by-step explanation:
Eliminate 1/2 from the side with w.
Subtract 1/2 from both sides:
[tex]3\frac{1}{4} -\frac{1}{2} =\frac{1}{2} -\frac{1}{2} +w[/tex]
[tex]2\frac{3}{4} = w[/tex]

What is the discount of a guitar with an original price of $95 and a discount of 15%.
Answer:
$80.75 dollars
Step-by-step explanation:
Given the following question:
Initial price = $95
15% discount
In order to find the answer, we have to find 15% of 95.
[tex]\frac{15\times95}{100} =15\times95=1425\div100=14.25[/tex]
[tex]95-14.25=80.75[/tex]
[tex]g=80.75[/tex]
The guitar (after a 15% discount) costs "$80.75 dollars."
Hope this helps.
Write an equation the describes the line passing through point (1/2, 0) with slope - 1
Answer:
Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]
Step-by-step explanation:
Equation of the line: [tex]y=mx+b[/tex]
Add in the slope in place of ([tex]m[/tex])
[tex]y=-1x+b[/tex]
Add in the x value of the given point in place of ([tex]x[/tex])
[tex]y=(-1)\frac{1}{2}+b[/tex]
Add in the y value of the given point in place of ([tex]y[/tex])
[tex]0=(-1)\frac{1}{2} + b[/tex]
—
Solve:
[tex]0=(-1)\frac{1}{2} +b[/tex]
Multiply -1 and [tex]\frac{1}{2}[/tex]
[tex]-1 *\frac{1}{2}=-\frac{1}{2}[/tex]
So,
[tex]0=-\frac{1}{2} +b[/tex]
Now, add [tex]-\frac{1}{2}[/tex] to 0
[tex]0=-\frac{1}{2} +b[/tex]
[tex]+\frac{1}{2}[/tex] [tex]+\frac{1}{2}[/tex]
---------------------------
[tex]\frac{1}{2} = b[/tex]
Replace ([tex]b[/tex]) with [tex]\frac{1}{2}[/tex]
Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]
Hope this helps! Brainliest would be much appreciated! Have a great day! :)

The proof of the law of sines was completed correctly by Kamala and the final step is to write the expression a/sinA = c/sinC.
What us the law of sines?The law of sines simply means the ratio between the sine of an angle and the side that's opposite it.
From the complete question, it can be deduced that the proof was correctly completed by Kamala. In her case, she correctly wrote that asinC = csinA and the next expression for the conclusion is that a/sinA = c/sinC.

2x = 2 x 25?
50 + ? = 150
50 + 100 = 150
x = 50?
2x + 50 = 150
2 x 50 + 50 = 150
100 + 50 = 150
The answer is x = 50.The measure of x is 50.
What are Vertical Angles?Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.
Using Vertical Angle property as
(50+ 2x) = 150
So, subtract 50 from side we get
50 + 2x - 50= 150 - 50
2x = 100
Now, divide both side by 2 we get
2x/2 = 100 / 2
x = 50

he area of a rectangular piece of metal is 20 square centimeters. The perimeter is 18 centimeters. What are the dimensions of the piece?
Answer:
5 cm by 4 cm
Step-by-step explanation
A = L x W 20 = L x W
P = 2L + 2W (18 = 2L + 2W)/2
9 = L + W W = 9 - L
20 = L (9 - L) 20 = 9L - L^2
L^2 - 9L + 20 = 0 (L - 4)(L - 5) = 0
L = 4 L = 5
The longer one is the length, so L = 5, and W = 4.
