Write the equation 7Y= 21X +0.7 in standard form identify a, B, and C
9514 1404 393
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.

Answer:
One Solutionx = -10Explanation:
7x + 12 = 5x − 8
Subtract 12 from both sides7x + 12 - 12 = 5x - 8 + 12
Simplify7x = 5x - 20
Subtract 5x from both sides7x - 5x = 5x - 20 - 5x

A lock has a code of 4 numbers between 1 and 20. If no numbers in the
code are allowed to repeat, how many different codes could be made?
There are 116,280 different codes that can be made with 4 numbers between 1 and 20 without repeating any number.
What are permutation and combination?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.

Show work!!!
Please anyone do this and put the right answer and show work I WILL MARK BRAINLIEST!!,
Answer:
14, 15, 16
Step-by-step explanation:
Let integers equal:
x, x + 1, x + 2
2x = 12 + (x + 2)
2x = 12 + x + 2
2x = 14 + x
2x - x = 14
x = 14
x = 14
x + 1 = 14 + 1 = 15
x + 2 = 14 + 2 = 16

Find the value of x
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
