Answer:
[tex]x=18[/tex]
Step-by-step explanation:
[tex](4x-11)\\(2x+25)[/tex]
According to the Alternate Exterior Angles Theorem, "when two lines are cut by a transversal, the resulting alternate exterior angles are congruent."
This means that the two expressions above are to be set equal to each other because they are representative of two alternate exterior angles, which are congruent:
[tex]4x-11=2x+25[/tex]
Add [tex]11[/tex] to both sides of the equation:
[tex]4x=2x+36[/tex]
Subtract [tex]2x[/tex] from both sides of the equation:
[tex]2x=36[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]2[/tex]:
[tex]x=18[/tex]
~
Check your work by substituting [tex]18[/tex] for [tex]x[/tex] in the initial equation:
[tex]4(18)-11=2(18)+25[/tex]
[tex]61=61[/tex]
It's correct!
Answer:
18
Step-by-step explanation:
From the given figure, we can see that angle (4x - 11) will be equal to angle 1 since they are corresponding angles
We notice that angle 1 is vertically opposite to angle (2x + 25)
Hence,
angle (4x - 11) = angle 1 = angle (2x + 25)
So, we can say that angle (4x - 11) = angle (2x + 25)
Now, solving for x:
4x - 11 = 2x + 25
2x = 36
x = 18

In Example 2, we saw that Airbus A330-300s seat 330 passengers and cost $250 million each, Boeing 767-300ERs seat 270 passengers and cost $200 million each, while Boeing Dreamliner 787-9s seat 240 passengers and cost $250 million each. You are the purchasing manager of an airline company and have a spending goal of $5550 million for the purchase of new aircraft to seat a total of 6750 passengers. Your company has a policy of supporting U.S. industries, and you have been instructed to buy twice as many Boeings as Airbuses. Given the selection of three aircraft, how many of each should you order?

Answer:
A330: 8B767: 9B787: 7Step-by-step explanation:
Let x, y, z represent the numbers of A330, B767, and B787 aircraft to order, respectively. The problem statement suggests 3 equations:
330x +270y +240z = 6750 . . . . . total seats
250x +200y +250z = 5550 . . . . . total cost (millions)
2x -y -z = 0 . . . . . . . . . . . . . . . . . . . ratio of orders
__
These can be solved by a variety of methods, including on-line equation solvers. If you want to do it by hand, substitution can help.
First divide by common factors:
11x +9y +8z = 225
5x +4y +5z = 111
Write an expression for z and substitute:
z = 2x -y
11x +9y +8(2x -y) = 225 ⇒ 27x +y = 225
5x +4y +5(2x -y) = 111 ⇒ 15x -y = 111
Adding the second of these to the first gives ...
(27x +y) +(15x -y) = (225) +(111)
42x = 336 . . . simplify
x = 8 . . . . . . . . divide by 42
15(8) -111 = y = 9
z = 2(8) -9 = 7
The solution to the equations is (x, y, z) = (8, 9, 7).
The order should be for 8 A330s, 9 B767s, and 7 B787s.

Xfinity claims that the performance package for the internet will get you a download speed of 100Mbps. In reality, each person who pays for that package has a slightly different internet speed. For a large data set of performance internet customers, the mean internet speed is 100Mbps, with extended deviation of 8Mbps. As soon as that the internet speeds in the data set can be modeled by a normal distribution.
What percent of Performance Package internet customers would be expected to have internet speeds between 84Mbps and 116Mbps? Be sure to also explain your process of getting the answer. Also, please show your work.
Answers
Answer: 95%
Step-by-step explanation:
mean = 100, standard deviation (sd) = 8
mean ± 1 sd = z-score of 1 which is 68%
100 ± 8 = 92 to 108
mean ± 2 sd = z-score of 2 which is 95%
100 ± 2(8) = 84 to 116
mean ± 3 sd = z-score of 3 which is 99.7%
100 ± 3(8) = 76 to 124
The internet speeds are between 84 and 118 which is 2 standard deviations from the mean, which is 95% of their internet customers.

What is a number line?In Mathematics, a number line can be defined as a type of graph that has a graduated straight line and comprises both positive and negative numbers that are placed at equal intervals along its length.
Generally speaking, a number line primarily decreases in numerical value towards the left and increases in numerical value towards the left.
Note: Each interval on this number line represents 1 unit.
Next, we would add the given numbers together in order to determine the distance between these points:
Distance = -5 1/2 + 2
Distance = -11/2 + 2
Distance = -7/2 or -3.5 units.
In conclusion, a distance of -7/2 or -3.5 units is shown in the number line shown in the image attached below.

The greatest number of rides you can go on at the carnival will be 17.6.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A carnival charges $6 for admission and $2.50 per ride. You have $50 to spend at the carnival.
Let x be the number of rides.
Then the equation is given as,
2.50x + 6 = 50
Simplify the equation, then we have
2.5x + 6 = 50
2.5x = 44
x = 17.6
Thus, the greatest number of rides you can go on at the carnival will be 17.6.

Which expression is equivalent to 3/5 divided by 7/9
Answers
Answer:
Step-by-step explanation:
its 27/35, so 27/1 * 1/35
The equivalent expression is obtained by changing the division sign to multiplication and taking the reciprocal of the denominator. Hence, we have 3/5 × 9/7 = 27/35
Denominator = 7/9Numerator = 3/5Reciprocal of denominator = 1 ÷ 7/9 = 9/7
Therefore, change the division operator to multiplication and use the reciprocal of the denominator.
3/5 ÷ 7/9 = 3/5 × 9/7
Hence, we have 3/5 × 9/7 = 27/35.
