Answer:
angle relationship: same-side interior
value of x: 40
Step-by-step explanation:
the horizontal lines are parallel and the vertical line is the transversal, so 3x+x+20=180. combine the x's and subtract 20 from both sides to get 4x=160. then divide both sides by 4 to get x=40.

Solve:
x + y = 7
3x - 2y = 11
By using Substituting method.
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \longmapsto x + y = 7 \: \: - - - (i)[/tex]
[tex]\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)[/tex]
By first equation,
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x = 7 - y[/tex]
Now, we can find the original value of y.
[tex]\sf \longmapsto 3x - 2y = 11[/tex]
[tex]\sf \longmapsto 3(7 - y) - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 3y - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 5y = 11[/tex]
[tex]\sf \longmapsto - 5y = 11 - 21[/tex]
[tex]\sf \longmapsto - 5y = - 10[/tex]
[tex]\sf \longmapsto y = \dfrac{ - 10}{ - 5} [/tex]
[tex]\sf \longmapsto y = 2[/tex]
Now, we can find the original value of x.
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x + 2 = 7[/tex]
[tex]\sf \longmapsto x = 7 - 2[/tex]
[tex]\sf \longmapsto x = 5[/tex]
Therefore, the values of x and y are 5 and 2 respectively.

Find the slope of the line satisfying the following conditions.
vertical through (6, -7)
Explanation:
The slope of any vertical line is always undefined. This is because [tex]\text{slope} = \frac{\text{rise}}{\text{run}}[/tex], and the "run" portion is 0. The run represents the change in x, but we don't have a change in x for vertical lines. The x value is always some constant.
So this is why the run is 0, and it leads to a division by zero error, causing an undefined slope.
A dog kennel charges a daily boarding rate as shown on the graph. use the information to mark 5-8 as true or false. if false, rewrite the statement correctly. 1. The dog kennel charges $60 per day. 2. The equation y = 30x can represent the graph. 3.Third is It costs $200 to board a dog for 7 days 4. The graph will contain the coordinate (9,270) Please give me all answers to all questions or i will go into trouble
The relationship between the cost charged for the daily boarding of dogs
by the kennel is a directly proportional relationship.
The correct responses are;
1. The dog kennel charges $60 per day is; False
Correct statement; The dog kennel charges $30 per day
2. The equation y = 30·x can represent the graph; True
3. It costs $200 to board a dog for 7 days is; False
Correct statement; It costs $210 to board a dog for 7 days
4.The graph will contain the coordinate point (9, 270); True
Reasons:
Points on the graph of the given graph of the Cost to Number of days are;
(2, 60), (4, 120)
The slope of the graph is [tex]m = \dfrac{120 - 60}{4 - 2} = 30[/tex]
Equation of the graph is therefore; y - 60 = 30·(x - 2)
Which gives;
y = 30·x - 2×30 + 60 = 30·x
The equation of the graph is; y = 30·x
Therefore, the statement;
2. The equation y = 30·x can represent the graph is; TrueThe cost of the dog kennel a day is given by the value of 'y', when x = 1, as
follows;
Cost per day, y = 30 × 1 = 30
The cost per day = $30 per day
Therefore;
1. The dog kennel charges $60 per day is; FalseThe correct statement is; The dog kennel charges $30 per day
3. The statement; It costs $200 to board a dog for 7 days is; FalseThe amount it costs to board a dog for 7 days is y = $30×7 = $210
Therefore, the correct statement is; It costs $210 to board a dog for 7 days
4. When x = 9, we have; y = 30 × 9 = 270Therefore, the statement; the graph will contain the coordinate point (9, 270) is; True

Find m Give explanation please
Answer:
m < FGN = 88°
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles (also known as remote interior angles).
Given the exterior angle, m <FGN = (7x + 18)°, and the two remote interior angles, m < E = 38° and m < F = (6x - 10)°:
The following equality statement can be established according to the exterior angle theorem:
m < E + m < F = m <FGN
38 + 6x - 10 = 7x + 18
Combine like terms:
28 + 6x = 7x + 18
Subtract 6x from both sides:
28 + 6x - 6x = 7x - 6x + 18
28 = x + 18
Subtract 18 from both sides:
28 - 18 = x + 18 - 18
10 = x
Next, substitute the value of x = 10 into the equality statement to determine whether it is the correct value of x, and to find the measures of < FGE and < F.
m < E + m < F = m <FGN
38° + (6x - 10)° = (7x + 18)°
38 + 6(10) - 10 = 7(10) + 18
38 + 60 - 10 = 70 + 18
88 = 88 (True statement).
Therefore, m < FGN = 88°

32 is 4 times as much as what number
Answer: 8
Step-by-step explanation:
The 4 times of the number 8 results to 32.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
32 is 4 times as much as what number
let the number be x.
So, 4 times of x = 32
4x = 32
Divide both side by 4.
4x/4 = 32/4
x= 8
Hence, the 4 times of the number 8 results to 32.

Answer:
For every two black kittens, there is one orange kitten.
Step-by-step explanation:
Simplify the ratio and put it in word form.
Answer:
For every three kittens there is one orange kitten
Step-by-step explanation:
The total number of kittens is equal to four black kittens + two orange kittens, which makes for six kittens.
So for every six kittens there are two orange kittens.
We can simplify this down further by dividing by the greatest common factor, 2.
So,
For every three kittens there is one orange kitten.

In January, 1950, the minimum wage was $.75. What should the minimum
wage be in July, 2009?
Answer:
On July 24, 2009, the federal minimum wage will increase to $7.25 per hour. This is the final step of a three-step increase passed in 2007 when the minimum wage was only $5.15. In this last step, about 4.5 million workers will receive a raise, providing an additional $1.6 billion annually in increased wages. However, when adjusted for inflation, the new federal minimum is still less than the minimum wage through most of the period from 1961 to 1981.
