i need to find the values of X but there isn’t another expression to find x for 180°
Answers
Answer:
x=5
Step-by-step explanation:
In this equation, we need to find x. According to the Vertical Angles Congruence Theorem, all vertical angles are congruent. Therefore, because angles (2x+12) and (8x-18) are vertical angles, they are congruent. We can set this up as an equation and simply solve for x:
2x+12=8x-18 Subtract 2x from both sides.
-2x -2x
12=6x-18 Add 18 to both sides.
+18 +18
30=6x Divide both sides by 6.
/6 /6
5=x
I hope this helps!! Have an amazing day :)
Answer:
x = 5
Step-by-step explanation:
The two angles have the same degree because of the Vertical Angles rule. This means that if angles are vertical, then they are congruent. Therefore, we can solve for x by setting the two angles equal to each other.
2x + 12 = 8x - 18
+ 18 + 18
2x + 30 = 8x
-2x -2x
30 = 6x
÷6 ÷6
5 = x
We can then double check this by inputing x back into the equations
2x + 12 = 2(5) + 12 = 10 + 12= 22
8x - 18 = 8(5) - 18 = 40 - 18 = 22
These check out so x = 5
I hope this helped :)

45% of the rooms in a hotel are booked. If 36 rooms are booked, how many rooms are in a hotel altogether?
Answers
Answer:
80 rooms
Step-by-step explanation:
since 45% of the rooms are booked, and 36 rooms are booked, then this means that 36 = 45% of x.
then, you we have 45% × x = 36
or [tex]\frac{45}{100}[/tex] × x = 36
Multiplying both sides by 100 and dividing both sides by 45,
we have x = 36 × [tex]\frac{100}{45}[/tex]
= [tex]\frac{3600}{45}[/tex]
x = 80

where is the question??
what is the slope of the line that passes through (-3,-3) and (-9,5)
Answers
The question gives us two points, (-3,-3) and (-9,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 -(-3)) ÷ (-9 -(-3))
= (5 + 3) ÷ (-9 + 3)
= - ⁴/₃
Checking my answer visually:
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. Once we have that equation, we can graph it to see if it passes through the two points. If it does, then we calculated the slope correctly.
⇒ y - (-3) = - ⁴/₃ (x - (-3) [ using the point (-3, -3)]
y + 3 = - ⁴/₃ (x + 3)

At an amusement park there's only enough room for 4500 people to be in it at any time. The manager has also worked out that there needs to be 2800 people in the park to make a profit after all the overhead costs and employee pay. If people are entering the park at a rate of 12 people a minute and there are 850 people in the park currently between how many minutes should the door stay open to let guests in?
(a) Translate the scenario above into a compound inequality involving the number of minutes, m, that the door has been open. Take into account both the fact that there must be a minimum of 2800 people and a maximum of 4500 people.
(b) Rewrite the inequality you found in part (a) using the AND connector and then solve the compound inequality.
(c) Write a solution set as a single statement using interval notation.
Answers
Using the concept of inequality, the number of minutes which ensures that the park makes profit while also ensuring that the park isn't overcrowded ls expressed below :
m ≤ 304m ≥ 163 (m ≥ 163) AND (m ≤ 304) 163 ≥ m ≤ 304Given the Parameters :
Total capacity = 4500Number of people required in park = 2800Entry rate, r = 12 people per minute Initial capacity, c = 850 Time, m =?The number of minute to keep the gates opened :
c + rm ≤ 4500
850 + 12m ≤ 4500
12m ≤ 4500 - 850
12m ≤ 3650
m ≤ (3650÷ 12)
m ≤ 304.16
Hence, the gates should be left opened for at most 304 minutes
B.)
In other to allow atleast 2800 in for profit sake
850 + 12m ≥ 2800
12m ≥ 2800 - 850
12m ≥ 1950
m ≥ 162.5
The gates should be opened for 163 minutes.
C.)
In other to make profit by allowing atleast 2800 people in while also ensuring that not more than 4500 people are in the park ; the inequality representing the number of minutes the gates should be open is :

A burrito costs $6.50 at a local restaurant.
Choose the table that correctly identifies three points on the graph
Answers
Answer:
The bottom left
Step-by-step explanation:
To solve we can create an equation to represent the problem given. In this case, the equation should be linear. This is because the total cost will change by the same amount each time the number of burritos changes. The slope (the amount the cost changes per burrito) is $6.50 because that is how much one burrito costs. So, the function would look like- y=6.5x. Plug in the x-values for the number of burritos and that will give the cost. Once you solve this equation, the bottom left chart is the only one that matches the values.

Help me decrease 25 by 30%
Answers
Step-by-step explanation:
Percentage decrease = 30% × 25
New value = 25 - Percentage decreaseNew value =
25 - Percentage decrease =
25 - (30% × 25) =
25 - 30% × 25 =
(1 - 30%) × 25 =
(100% - 30%) × 25 =
70% × 25 =
70 ÷ 100 × 25 =
70 × 25 ÷ 100 =
1,750 ÷ 100 =
17.5
Absolute change (actual difference) =
New value - 25 =
17.5 - 25 =
- 7.5
Answer:
25 decreased by 30% equals 17.5
Step-by-step explanation:
To solve this, we need to make our equation to solve.
x/25=30/100
We did x because we don't know what 30% of x is. The 25 shows the total, while the right side shows the percent.
Now cross multiply
100x=750
Now divide both sides by 100.
you will get x=7.5
So now we know that 7.5 is 30% of 25. Now, subtract 7.5 from 25 in order to find out what 25 decreased by 30% is.
25-7.5=17.5
So the answer is 17.5
What is the distance between points N and M?
A. 4.2
B. 5.8
C. 11.9
D. 11.6
Answers
Answer:
Answer B is closest: 5.8 units
Step-by-step explanation:
Points M and N appear to lie in the same plane, so this problem is a 2-dimensional one. The distance along the x axis from N to the origin is 5 units and that along the y axis from the origin to M is 3 units. We apply the Pythagorean Theorem, as follows:
d = √(3² + 5²), or
d = √34, which is approximately 5.83 units. Answer B is closest: 5.8 units.

Write the solution in interval notation. with explanation.
Answers
Answer:
(-infinity, 2) U [-3]
Step-by-step explanation:
Step 1: we want to solve both equations for x. To do so, get the x variable by itself in both equations.
1.) 3x+4 = 5x+10
-6 = 2x (subtract 10 from both sides and 3x from both sides)
-3 = x (divide 2 from both sides)
2.) -5x + 7 > -3
-5x > -10 (subtract 7 from both sides)
x < 2
(divide both sides by -5, notice that dividing by a negative by a negative number flips the direction on > to < .)
Step 2: apply interval notation to these answers. Since x DOES equal -3 in equation one, it'll be in a bracket. On the contrary, since x has to be LESS THAN 2, it will have a parentheses.
So, our answer is: (-infinity, 2) U [-3]
*note the parentheses around infinity because something cannot equal infinity, it's not just one number*

Answer:
x = 1/4
Step-by-step explanation:
Given 2/x = 8:
Multiply both sides by x to eliminate the fraction:
[tex](x)(\frac{2}{x}) = 8(x)[/tex]
2 = 8x
Divide both sies by 8 to solve for x:
[tex]\frac{2}{8} = \frac{8x}{8}[/tex]
1/4 = x
To verify whether it is the correct answer, substitute x = 14 into the original equation:
[tex]\frac{2}{x} = 8[/tex]
[tex]\frac{2}{\frac{1}{4} } = 8[/tex]
2 * 4/1 = 8
8 = 8 (True statement).
Therefore, the correct answer is x = 1/4
