Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23
3(23) - 19 = 50
50 + y = 180
180 - 50 = y
y = 130

The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots?
(x + 7) (x – 3) = 0
(x - 7) (x + 3) = 0
(x – 7) (x – 3) = 0
(x + 7) (x + 3) = 0
Answers
Explanation: Put both equations equal to 0, so it looks like this: (x - 7) = 0 (x + 3) = 0
It doesn’t matter what you do first but I’ll start with (x - 7) = 0
First you remove the parenthesis
x - 7 = 0
Next you add the 7 on both sides. You do this to cancel the 7 so that the x is by itself.
x = 7
It’s the same thing for the (x + 3) = 0 but I’ll show you anyways
Remove parentheses
x + 3 = 0
Subtract the 3 from both sides that way the 3 cancels out and the x is on its own
x = -3

Question Says:-An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?
Answer:-See, let us consider the sides as l as per question.
And, perimeter as p as per question.
We know that:-
The sum of all the boundary gives us the perimeter of the figure.
It is Equilateral Triangle, so the equation will be:-
[tex]l + l + l = p[/tex]
Now, adding it up, we get
[tex]3l = p[/tex]
So, 3l=p relates the side and perimeter.
Hope it helps :)

Answer:
x = 25
Step-by-step explanation:
3x + 5 + 5x - 25 = 180 (collect like terms)
8x - 20 = 180 (add 20 on both sides)
8x = 200 (divide by 8 on both sides)
x = 25
Since they are supplementary that mean together they add up to 180 so that's why I added them together.

Answer:
The answer is 12Step-by-step explanation:
The slope of a line given two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,3) and (0,−9)
The slope is
[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute
Answers
Answer:
$3
Step-by-step explanation:
To find the value of the tip, multiply 200 by 15%.
200 x 15% = 30
Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)
30 / 10 = 3
Each person should contribute $3 toward the tip.
Each person will contribute $23.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Bill= $200
Tip= 15%
So, the amount of bill be paid after tip
= 200+ 200 x 15%
= 200+ 200 x 15/100
= 230
Now, each of them have to pay
= 230/ 10
= $23
Hence, Each of them paid $23.
