Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:
slope = 4/5
Step-by-step explanation:
The best way to find the slope with just a line is to pick the most direct points on the graph, meaning points that are not in between numbers but right on the graph lines
y value - y value over x value - x value
Points: (-2,0) and (3,4)

Answer:
180
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.When side lengths are given, add them together.
Solve for a missing side using the Pythagorean theorem.

Answer:
For the first picture: m angle t=36 and m angle v=54
For the second picture:m angle P=55 m angle Q=81 and m angle QPR=180
Step-by-step explanation:
For the first picture, you had to do 2x+3x+90=180
We got the 90 from the right triangle.
Then you combine like terms, which was then 5x=90=180
Then, you subtract the 90 from both side, leaving 5x=90
Divide 90 by 5, which gives you x=18
For both the answers, you had to do 2(18) for T and 3(18) for V
The second picture, you did (8y + 1) + (5y + 5)= 136
You combine like terms, which levas you with 13y + 6 = 136
You subtract 6 from both sides, leaving you with 13y= 130
Divide 130 by 13, which is 10 so y=10
You then replace the y for (8y + 1) to 10 and solve
As well as for (5y + 5), you replace the y with 10 and solve
And m angle QRP is 180 because every triangle has a total of 180 degrees

Step-by-step explanation:
x= -3.6 y= 14.4
HOW I SOLVED IT
-3.6 x 3 = -10.8 2 x 14.4 = 28.8 - 10.8 = 18 so correct since it must equal to 18
-2/3 x -3.6 =2.4 + 12 = 14.4 so correct since y = 14.4

Answer:
If it's 16, then it's -4 > x
Step-by-step explanation:
Ignore the inequality sign first and solve 12 = -3x
This would equal -4 = x
Now, when you divide or multiply both sides by a negative, you have to change the inequality sign so you change it from -4 > x to -4 < x
Which sequence of transformations will map figure Q onto figure Q′?

A) Translation of (x, y + 2), reflection over x = 1, and 180° rotation about the origin
B) Translation of (x, y − 2), reflection over x = 1, and 180° rotation about the origin
C) Translation of (x, y − 2), reflection over y = 1, and 180° rotation about the origin
D) Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin
Answer:
Which sequence of transformations will map figure Q onto figure Q′?
Its D.Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin
Step-by-step explanation:
The sequence of transformations that will map figure Q onto figure Q′ : 'Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin.'
The correct answer is option (D)
What is translation?"It is a geometric transformation in which the displacement of a figure from one place to another."
What is reflection?"It is a geometric transformation where all the points of an object are reflected on the line of reflection."
What is rotation?"It is a transformation in which the object is rotated about a fixed point."
For given question,
Quadrilateral Q with coordinates (-9, 2) ,(-6, 4) ,(- 4, 4) , and (-2, 2) Quadrilateral Q' with coordinates (2, 2), (4, 4), (6, 4), and (9, 2)
Consider a point (-4, 4) of quadrilateral Q. If we reflect Q over x = 1, then it would push the x coordinate of (-4, 4) to new x value 5 units to the right of x = 1, which is x = 6, and 180 rotation would make x = -6 But x = -6 is not in Q' . So it must be reflection over y = 1.Consider the transformations at option C, First translate to (x, y - 2) So, the translation of (-4,4) becomes (-4, 2), reflection over y = 1 gives (-4, 4), and 180° rotation about origin gives (4, -4) which is not the coordinate of Q'Now, consider the translation of (x, y + 2) So, the translation of (-4, 4) becomes (-4, 6), reflection over y = 1 gives (-4, -4), and 180° rotation about origin gives (4, 4) which is the coordinate of Q'Therefore, the sequence of transformations that will map figure Q onto figure Q′ : 'Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin'
The correct answer is option (D)

Consider the enlarged triangle.
A smaller triangle has side lengths 4, 5, 3. A larger triangle has side lengths 8, 10, 6.
Which steps should be used to find the perimeter? Check all that apply.
Find the scale factor: enlarged over original = 6 over 3 = 2
Find the scale factor: enlarged over original = 3 over 6 = one-half
Calculate the perimeter of the original figure.
Divide the perimeter of the original figure by the scale factor.
Multiply the perimeter of the original figure by the scale factor.
Find the scale factor: StartFraction enlarged over original EndFraction = StartFraction 6 over 3 EndFraction = 2
Calculate the perimeter of the original figure.
Multiply the perimeter of the original figure by the scale factor.
Step-by-step explanation:
A, C, D
The steps which could be used to find the perimeter are Find the scale factor: enlarged over original = 6 over 3 = 2, Calculate the perimeter of the original figure and Multiply the perimeter of the original figure by the scale factor.
What is Scale Factor?Scale factor is the ratio of the dimension of the given original object and the dimension of the new object from the original.
Given that,
A smaller triangle has side lengths 4, 5, 3. A larger triangle has side lengths 8, 10, 6.
First find the scale factor.
Scale factor of enlarged over original = 8/4 = 10/5 = 6/3 = 2
Now, find the perimeter of the original figure.
Perimeter of the original figure = 4 + 5 + 3 = 12
Now.
Perimeter of enlarged figure = Scale factor × Perimeter of original figure
= 2 × 12
= 24
Hence the correct steps are first, third and last step.

Describe how to create an equivalent equation from an equation that has fractions or decimals. Explain how to decide what numbers to use to multiply. Also, explain any other important things to remember when using this process.
Answer:
i hope this helps :)
Step-by-step explanation:
So, with an equation with decimals, we can use the same method we used to clear fractions—multiply both sides of the equation by the least common denominator. Look at the decimals and think of the equivalent fractions. Notice, the LCD is 100. By multiplying by the LCD, we will clear the decimals from the equation.
Answer: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
Steps: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
For example:
[tex]\frac{2}{3}x-\frac{5}{4}=\frac{1}{2}[/tex]
Here denominators are 3,4 and 2. So the LCM of them is = 12
Multiply both sides by 12.
[tex]12(\frac{2}{3}x-\frac{5}{4})=12(\frac{1}{2})\\8x-15=6[/tex]
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
For example: 0.324x - 0.92 = 0.526
Here maximum number of places after decimal is = 3.
So we will multiply both sides by 1000.
1000(0.324x - 0.92) = 1000(0.526)
324x - 920 = 526

Keith and his 6 friends are taking a trip. The total cost of the trip is $1,145.55. The total cost of the tickets for the amusement park was $341.25. The total cost of three hotel rooms was $454.65. The total cost for the show they were going to see was $153.65. The rest of the money they paid was used to purchase gas for their trip. Use this information to answer the questions below.
Answer and explanation:
Question is incomplete
Question will likely ask how much is the rest of the money paid for gas.
We use algebra to find how much is the rest of the money paid for gas
So given
total cost of the trip = $1,145.55
total cost of tickets for amusement park = $341.25
The total cost of three hotel rooms = $454.65
total cost for the show they were going to see = $153.65
Let's call rest of money spent on gas x
Hence the equation for total cost with all expenditures,
$341.25+$454.65+$153.65+x=$1,145.55
Solve for x
$949.55+x=$1145.55
x=$1145.55-$949.55
x= $196
Therefore amount spent on gas for the trip =$196
