Answer:
there is no solution
Step-by-step explanation:
You would use distributive property first to get
12x+36 = 8x+36 + 4x
by combining like terms, you would get 12x+36 = 12x+36, meaning there is no solution to this equation

if angle 1= 135, what is the measure of angle 2, and give your reason. Use the picture i used
Answer:
The measure of m∠2 is:
m∠2 = 45°Step-by-step explanation:
A straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line.
Given
The angle ∠ 1 = 135°.
It is clear that angles ∠ 1 and ∠ 2 lie on a straight line.
We know that a straight line is basically a straight angle i.e. 180°.
Thus,
The sum of angles ∠ 1 and ∠ 2 will be 180°.
i.e.
m∠1 + m∠2 = 180°
substitute m∠1 = 135° in the equation
135° + m∠2 = 180°
subtract 135° from both sides
135° + m∠2 - 135° = 180° - 135°
m∠2 = 45°
Therefore, the measure of m∠2 is:
m∠2 = 45°what is the answer to this question

A selection box contains four types
of sweets: 6 caramels, 7 chocolates,
4 bonbons and 3 nougats
What fraction are carame/s
b. What fraction are not caramels?
Answer:
3/10 are caramel 7/10 are not caramel
Step-by-step explanation:
First you need to work out the total of sweets that is 6+7+4+3=20 sweets. Now it says that there are 6 caramels so you need to put 6/20 which can be simplified to 3/10. For b you have to work out the fraction that is not caramel so for this you have to add up 7+4+3=14 put 14/20 this can be simplified to 7/10.

The length of each side of the playground is 20 ft.
What is a Square?
Square in geometry is a special kind of rectangle with four equal sides and four right (90°) angles.
Given is a square playground has an area of 400 square feet.
Area of square playground = 400 ft².
Area of square is given by square of the length of its sides. If 'a' is the side of a square, then mathematically we can write -
A [S] = a²
Using the formula discussed above -
a² = 400
a = √400
a = 20 ft
Therefore, the length of each side of the playground is 20 ft.

Work out the surface area of this cylinder.
Answer:
Step-by-step explanation:
Total surface = πr² + 2πrh
Surface area = 22/7 × 6 × 6 + 2 × 22/7 + 25
So 22/7 × 12 + 44/7 × 25
Therefore this will give us 37.71 + 157.14
Therefore the total surface area of the cylinder is 194.85 cm².

The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides

y = -x²+4
y = 2x+1
solve the system of equations
The solution of the equation as x= -1 then y= -1 and x= 3 then y = 7.
What is Equation?It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have equations y = -x²+4 and y = 2x+1.
So, 2x + 1 = -x²+4
x² - 4 -2x +1 = 0
x²-2x -3 = 0
Now splitting the mid term we get
x²-2x -3 = 0
x²-3x +x -3 = 0
x(x-3 ) + 1 (x-3)= 0
(x+ 1) (x-3) = 0
x= -1 or 3.
and, when x= -1 then y= -1
when x= 3 then y = 7.

Find the measure of the exterior angle.
Answer:
120 degrees
Step-by-step explanation:
Because the triangle is a right triangle, it can be either a 45,45,90 triangle or a 30,60,90 triangle. I tested this problem with each scenerio, and I believe that it is a 30, 60, 90 triangle, with the top angle being 30 degrees, thus, making x=30. For the exterior angle, we'd multiply 4 by 30 to get 120 degrees.
I checked my answer by adding 120 to 60 (that's the degrees of the right hand corner of the triangle), which added to 180 degrees (aka a flat line), which verifies my answer.
I hope this helps! :)
WILL GIVE BRAINLIEST! Six numbers form an arithmetic sequence with a common difference of 4. The sum of these numbers equals to 12. What are the six numbers?
Answer: -8,-4,0,4,8,12
Step-by-step explanation:
The six numbers of the arithmetic progression are -8, -4, 0, 4, 8, 12
Arithmetic sequence:aₙ = a + (n - 1)dwhere
a = first term
d = common difference
n = number of terms
d = 4
first term = a
2nd term = a + 4
3rd term = a + (3 - 1) 4 = a + 8
4th term = a + (4 - 1) 4 = a + 12
5th term = a + (5 - 1) 4 = a + 16
6th term = a + (6 - 1) 4 = a + 20
sum of its 6 terms = 12
Therefore,
a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12
6a + 60 = 12
6a = 12 - 60
6a = -48
a = -48/6
a = -8
2nd term = -8 + 4 = -4
3rd term = -8 + 8 = 0
4th term = -8 + 12 = 4
5th term = -8 + 16 = 8
6th term = -8 + 20 = 12
