First of all let's review some vocabulary:
Supplementary : a fancy word that means "the angles add up to 180" .
If we know that the total is 180 , then the values of A and B are .......
Let's set up an equation :
5x + x = 180
5x symbolizes "The measure of angle A is 5 times "
X symbolizes "the measure of angle B"
And 180 "the total"
Now we solve the equation
5x+x=180
6x=180
6x/6 =180/6
X=30
We just found the measure of angle B , now let's find A.
So the measure if angle A is 5 times the measure of angle B . We already know the measure of angle B , so we just multiply 30 by 5.
30 times 5=150
Angle A=150
Angle B=30
Let's check the answers
150 + 30 = 180
They add up to 180 , which means they are correct .

Angle A is 150
Angle B is 30 
Supplementary= 180, so....
Angle A + Angle B = 180
150 + 30= 180

hope this helps

The lengths and widths of two rectangles are proportional. One
Rashid [163]

The width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.

<u>Explanation:</u>

Given:

Two rectangles are proportional.

Length and width of 1 rectangle = 6 : 8

Dimensions of the other rectangle = ?

Let length and width of the other rectangle be x : y

According to the question:

\frac{6}{8} :\frac{x}{y}

\frac{6}{8} X \frac{y}{x}

So, the width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.

What is the equation of the line that passes through (-2, 2) and (1, -4)?
poizon [28]

Answer:

y = - 2x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁  = (- 2, 2) and (x₂, y₂ ) = (1, - 4)

m = \frac{-4-2}{1+2} = \frac{-6}{3} = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 2), then

2 = 4 + c ⇒ c = 2 - 4 = - 2

y = - 2x - 2 ← equation of line

If 14y - 4 = 24y + 26 , then 12y =
harkovskaia [24]
Solutions 

To solve the equation we have to isolate 12y

14y - 4 = 24y + 26&#10;&#10;-4 - 26 = 24y - 14y&#10;&#10;-30 = 10y&#10;&#10;10y = -30&#10;&#10;y =- -30/10&#10;&#10;y = -3&#10;&#10;12y =12/-3&#10;&#10;12y = -36&#10;&#10;Therefore, 12y = -36

Simplify (x - y + 1) - (x + y - 1)
andrey2020 [161]
First, distribute the minus sign across the second set. So you have:

x - y + 1 - x - y + 1

Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2

So we have -2y+2

Hope that helps.

Grace is three times as old as Hans, but in 5 years she will be twice as old as Hans is then. How old are they now? Set up an th
frosja888 [35]

Answer:

3x - y = 0; 2x - y = -5

Step-by-step explanation:

Let x be the present age of Hans and y be the present age of Grace,

Since, in present Grace is three times as old as Hans,

⇒ y = 3x

⇒ 3x - y = 0

Now, after 5 years,

The age of Hans = x + 5,

And, the age of Grace = y + 5

Also, in 5 years Grace will be twice as old as Hans is then,

⇒ y + 5 = 2 ( x + 5 )

⇒ y + 5 = 2x + 10

⇒ 2x - y = -5

Hence, the required system of linear equations is,

3x - y = 0; 2x - y = -5
