Answer:

x = 30

Step-by-step explanation:

So we're going to start by finding the other angles of the triangle which x is part of. So we know that a line adds up to 180 degrees. So we can find the angle that's close to N. If you know which one I'm talking about.

105 + 45 = 150. So then we can subtract 150 from 180

180 - 150 = 30

And for the angle at angle L, it's also 90 degrees.

So we know that the angles that add up so far are 120.

Now we'll make an equation:

2x + 120 = 180

Because all angles of a triangle add up to 180

So we subtract 120 from both sides

2x = 60

Now we divide 2 form both sides.

x = 30

So, x = 30

Hey there!

The answer is 30 degrees.

First, we will start by figuring out the other angle, N:

We can do this by making an equation. We know that angles connected by a straight line form a total of 180 degrees, and the line OK is a straight line, and the angles on it are 105, 45, and N. To solve for N, we make the equation:

180 = 105 + 45 + n

180 = 150 + n

30 = n

Now, we know that the missing angle N is 30. Also, we know that the angles in a triangle add up to 180, and we have all the angles in the left triangle except "2x", so we solve for it by making the equation:

180 = 30 + 90 + 2x

180 = 120 + 2x

60 = 2x

30 = x

There are 116,280 different codes that can be made with 4 numbers between 1 and 20 without repeating any number.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Here,
To find the number of different codes that can be made with 4 numbers between 1 and 20 without repeating any number, we can use the permutation formula, nPr = n! / (n-r)! where n is the total number of items and r is the number of items we want to choose.

In this case, we have n = 20 (the total number of numbers we can choose from) and r = 4 (the number of numbers we need to choose).

So, the number of different codes that can be made is:

20P4 = 20! / (20-4)! = 20! / 16! = 20 × 19 × 18 × 17 = 116,280

Therefore, there are 116,280 different codes that can be made with 4 numbers between 1 and 20 without repeating any number.

Answer:

x+y< 400

Step-by-step explanation:

x = Number of lawn tickets sold

y = Number of seat tickets sold

We are told that: Fewer than 400 tickets in total were sold.

Hence, this means that, less than 400 tickets were sold.

The symbol for less than = <

Therefore, the equation you could make for fewer than 400 tickets were sold is given as:

x+y< 400

Answer: x+y< 400

Answer:

The equation of the line with slope m = 2 and passing through the point (1, 1) will be:

[tex]y = 2x[/tex]

Step-by-step explanation:

We know that the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

The formula [tex]y-y_1=m\left(x-x_1\right)[/tex] is termed as the point-slope form of the line equation because if we know one point on a certain line and the slope of that line, then we can easily get the line equation with this formula and, hence, determine all other points on the line.

For example, if we are given the point (1, 1) and slope m = 2

Then substituting the values m = 2 and the point (1, 2)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 2 = 2(x-1)[/tex]

[tex]y - 2 = 2x-2[/tex]

[tex]y = 2x-2+2[/tex]

[tex]y = 2x[/tex]

Therefore, the equation of the line with slope m = 2 and passing through the point (1, 1) will be:

[tex]y = 2x[/tex]

Answer:

  30x -10y = -1

  (A, B, C) = (30, -10, -1)

Step-by-step explanation:

We can multiply by 10 to clear the fraction:

  70y = 210x +7

Now, we can remove a common factor of 7 from the coefficients:

  10y = 30x +1

Subtracting 10y+1 puts this in standard form.

  30x -10y = -1

The coefficients are A=30, B=-10, C=-1.
