3 x + y = 23
answered: faith1993
Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
answered: evelynalper08
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7 2/3x + y = 7(2/3x + y = 7)32x + 3y = 21
Y= -2/3*x+7 | *3
3y= - 2x+21 | +2x
3y+2x=21 this is the correct answer
You multiply everything by 3 which equals 3y=2x+21 then you switch 21 and 3y which equals -21=2x-3y. Hope this helps
1 Answer. The equation in standard form is 23x−y=7 .
Step-by-step explanation:
answered: Guest
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
\frac{2}{5}=\frac{x-18}{x}
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:

Your math test scores
are 81%, 77%, 79%,
83%, and 70%. Which
measure of central
tendency should tell
your parents to make
your math test scores
seem highest?
Answers
Answer:
Median
Step-by-step explanation:
Mean: (81+77+79+83+70)/5 = 78
Median: 70, 77, 79, 81, 83
Mode: None
Therefore, the median is the better measure of central tendency you should tell your parents to make your math test scores seem highest.
Answer:
if you choose mean, your score would be 78 because 81+77+79+83+70=390, divide that by 5 and you get 78, your median would be the 79, and if you choose mode, you really couldn't calculate it since there is only one of each number, therefore the best choice is the median of 79%

I believe that 50,000,000 is 49,999,500 times greater than 500.

If you divide the two:
50,000,000 ÷ 500 = 100,000.

Given: α is an angle in the second quadrant, csc α = 25/7; β is an angle in the first quadrant, cos β = √2/2. The value of tan ( α - β ) = _____.
-3/17
29/17
-31/17
15/17
Answers
Answer:
-31/17
Step-by-step explanation:
csc²α-cot²α=1
cot²α=csc²α-1=(25/7)²-1=(625-49)/49=576/49
α is in 2nd quadrant so cotα is negative.
cot α=-√(576/49)=-24/7
tan α=-7/24
cos β=√2/2
sec β=2/√2=√2
sec²β-tan ²β=1
tan ²β=sec²β-1
tan²β=(√2)²-1=2-1=1
β is in 1st quadrant ,so tan β is positive.
tan β=1
[tex]tan (\alpha -\beta )=\frac{tan \alpha -tan \beta }{1+tan \alpha tan \beta } \\=\frac{\frac{-7}{24} -1}{1+(\frac{-7}{24}) (1)} \\=\frac{-7-24}{24-7} \\=\frac{-31}{17}[/tex]

The perimeter of the polygon is_______units.
Answers
Answer:
3 units
Step-by-step explanation:
Since the sides are congruent, then
5 - 2x = - 4x + 9 ( add 4x to both sides )
5 + 2x = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Then
5 - 2x = 5 - 2(2) = 5 - 4 = 1

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.
So, a traingle is 180 degrees.
A line is also 180 degrees.
We know that the angles that make up the triangle are 46, 90, and a missing angle
We need to find the missing angle to find x
To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.
So:
180-90
=
90
90-46
=
44
So we know the missing angle is 44 degrees.
Let subtract the missing angle(44 degrees) by the 180 degrees of the line:
180-44
=
136
THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER
So x equals 136. This is the missing angle x.
So, remember, both the line and the traingle are 180 degrees.
They both need to find the missing value, which we know is 44
The rest of both the triangle and line is 136 degrees.
Well, 136 degrees on the triangle is the known 90+46 degrees.
Since this will be the same on the line, we can think of x as:
90+46
This looks like answer 1.

A. 85

explanation:
(73+84+91+78+x)/5 = 85
Answer:
[tex]99[/tex]
Step-by-step explanation:
The average of an [tex]x[/tex] amount of values is equal to the sum of all the values divided by [tex]x[/tex]. Thus, for any five scores to have an average score of 85, the sum of the scores must be [tex]85\cdot 5=425[/tex]
