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.

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]

Help!!! Use 1st and 2nd differences to determine if the following table is linear, quadratic or neither.
Given the second difference, the table is quadratic.
What are linear and quadratic equations?A linear function is a function that has a single variable raised to the power of 1. An example is x + 2. A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is 2x² + 10x + 25.
What are the first and second differences?First differences:
21 - 11 = 10
35 - 21 = 14
53 - 35 = 18
75 - 53 = 22
Due to the fact that the first difference is not the same, the function is not a linear function.
Second difference:
14 - 10 = 4
18 - 14 = 4
22 - 18 = 4
Due to the fact that the second difference is fairly constant, the function is a quadratic function.

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."

A watch, after allowing a discount of 15% on its marked price, was sold at a gain of 20%. Had it been sold after allowing 25% discount there would have been gain of Rs. 120. Find the cost price of the watch.
Answer:
Answer:1200
Step-by-step explanation:
Consider the cost price to be x.
1st equation x - (15/100)x = x + (20/100) ...15% discount and gain of 20%
2nd equationx - (25/100)x = x + 120 ....25% discount and a gain of 120Rs
Solving above equations by subtracting we get
(10/100)x = (20/100)x - 120
Solving LHS and RHS..(10/100)x =120
x=1200

Step-by-step explanation:
Given the following question:
[tex]A=s^2[/tex]
In order to find the area of the square we have to multiply two of the lengths by itself.
[tex]A=s^2[/tex]
[tex]A=100^2[/tex]
[tex]A=100\times100[/tex]
[tex]100\times100=10000[/tex]
