Problem 1
The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.
6x = 30
x = 30/6
x = 5 is the answer
====================================================
Problem 2
The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).
So,
5x+(3x+12) = 180
8x+12 = 180
8x = 180-12
8x = 168
x = 168/8
x = 21 is the answer
Which equation in point-slope form contains the point (4, –1) and has slope 3?
y + 1 = 3(x – 4)
y – 4 = 3(x + 1)
y – 1 = 3(x + 4)
y + 4 = 3(x – 1)
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)

Can somebody who knows how to do probability please help answer these questions correctly? Thanks! (Btw the P= probability)
WILL MARK BRAINLIEST WHOEVER CAN ANSWER FIRST :DDDDD!!!!!!!
Answer:
P(2): 1/5
P(4): 1/5
P(odd number): 3/5
P(whole number): 5/5
P(6): 0/5
P(2 or 3): 2/5
Step-by-step explanation:
There are 5 equal sections in this circle. So, the probability to land in each section is 1/5.
The odd numbers are 1, 3, and 5. Since each section is 1/5, you add
1/5 + 1/5 + 1/5 = 3/5. That is the probability that you will land in any odd number.
Because all the numbers listed are whole numbers, no matter where the spinner lands it will be a whole number. So, the probability is 5/5 for whole numbers.
Since 6 is not a section, it's probability will be 0/5 (or you can just put 0).
"Or" means you add the two probabilities. Add the probability of landing on 3 (which is 1/5) to the probability of landing on 2 (which is also 1/5). So, you get 2/5.
Answer:
17. 1/5
18. 1/5
19. 3/5
20. 1
21. 2/5
Darren has a wooden board that is Three-fifths of a meter long. He cuts the board into 3 equal parts. How long is each section of board?
Answer:
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
Step-by-step explanation:
3/5 divided by 3 is the equation we have to do.
3/5 divided by 3 is also equal to 3/5 times the reciprocal of 3 or 1/3
3/5 * 1/3
3*1 = 3
5*3 = 15
3/15 which can simplify to 1/3. (divide numerator and denominator by 3.)
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
the ratio of the ages of kapil and ramu is 4:5. After five years, the sum of their ages is 46 years. find the present ages
Answer:
Step-by-step explanation:
Let the age of Kapil is 4x and that of Ramu is 5x.
After 5 years,
Kapil's age = 4x+5
Ramu's age = 5x+5
ATQ,
4x+5+5x+5 = 46
9x+10 = 46
9x = 36
x = 4
Present age of Kapil = 4x = 4(4) = 16 years
Present age of Ramu = 5x = 5(4) = 20 years
Write and solve the equation to find the value of x and the missing angle measures.
Answer:
x = 8
The missing measures are 85 degrees
Step-by-step explanation:
Since 9x + 13 and 11x - 3 are on opposite sides, they are equal, so
9x + 13 = 11x - 3
Subtract 13 from both sides:
9x = 11x - 16
Subtract 11x from both sides:
-2x = -16
Divide both sides by -2:
x = 8
The angle measures are
9(8) + 13 = 72 + 13 = 85
11(8) - 3 = 88 - 3 = 85
Answer:
9x+13 = 11x-3
x = 8
The angles are 85
Step-by-step explanation:
The angles are vertical angles so they are equal
9x+13 = 11x-3
Subtract 9x from each side
9x+13 -9x = 11x-9x-3
13 = 2x-3
Add 3 to each side
13+3 = 2x-3+3
16 =2x
Divide by 2
16/2 = 2x/2
8 =x
11x-3 = 11(8) -3 = 88-3 = 85

Mrs. Chin paid a 20 percent tip on the bill for lunch. Percents Total 20% 20% 20% 20% 20% 100% $2.75 $2.75 $2.75 $2.75 $2.75 If the tip amount was $2.75, what was the bill for lunch before the tip was added to it?
Answer: $13.75
Step-by-step explanation:
Since Mrs. Chin paid a 20 percent tip on the bill for lunch and the tip amount was $2.75, then the bill for lunch before the tip was added to it will be calculated thus:
Let the bill for lunch be represented by x. Therefore,
20% of x = $2.75
20/100 × x = $2.75
0.2 × x = $2.75
0.2x = $2.75
x = $2.75/0.2
x = $13.75
Therefore, the bill is $13.75 before the too was added.

Answer:
cos(θ) = 3/5
Step-by-step explanation:
We can think of this situation as a triangle rectangle (you can see it in the image below).
Here, we have a triangle rectangle with an angle θ, such that the adjacent cathetus to θ is 3 units long, and the cathetus opposite to θ is 4 units long.
Here we want to find cos(θ).
You should remember:
cos(θ) = (adjacent cathetus)/(hypotenuse)
We already know that the adjacent cathetus is equal to 3.
And for the hypotenuse, we can use the Pythagorean's theorem, which says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, this is:
3^2 + 4^2 = H^2
We can solve this for H, to get:
H = √( 3^2 + 4^2) = √(9 + 16) = √25 = 5
The hypotenuse is 5 units long.
Then we have:
cos(θ) = (adjacent cathetus)/(hypotenuse)
cos(θ) = 3/5

Triangle ABC is given by the points A(3, 2), B (4, 4), and C(5, 1). Select True or False for each statement.
Answer:
C. The perimeter of ΔABC is 7.6 units.
Step-by-step explanation:
Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.
A. The perimeter of ΔABC is 9.9 units.
B. ΔABC is an equilateral triangle.
C. The perimeter of ΔABC is 7.6 units.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.
The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:
[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Given the vertices of triangle ABC as A(3, 2), B(4, 4), and C(5, 1). Therefore we have to calculate the side lengths of the triangle:
[tex]AB=\sqrt{(4-3)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5} \\\\AC=\sqrt{(5-3)^2+*(1-2)^2}=\sqrt{4+1}=\sqrt{5} \\\\BC=\sqrt{(5-4)^2+(1-4)^2}=\sqrt{1+9}=\sqrt{10}[/tex]
1) Perimeter of the triangle = AB + AC + BC = √5 + √5 + √10 = 7.6 units
2) Since only two sides of the triangle are equal (i.e. AB = AC), hence the triangle is an isosceles triangle.
