x = 12
angle A = 30 degrees
===========================================================
Explanation:
Check out the attached image below.
Note the pair of (8x+4) angles which are congruent vertical angles.
Also, notice that 50+130 = 180 since those adjacent angles are supplementary. In other words, they form a straight line.
Now that we know the expressions for each interior angle, we add them up and set the sum equal to 180. Recall that for any triangle, the interior angles always add to 180.
Let's solve for x
(3x-6) + (8x+4) + (50) = 180
11x + 48 = 180 .... combine like terms
11x = 180-48 ..... subtract 48 from both sides
11x = 132
x = 132/11 ..... divide both sides by 11
x = 12
Use this to find the value of angle A
A = 3x-6
A = 3*12-6
A = 36 - 6
A = 30
For the sake of completeness, let's find 8x+4 as well. This part is optional
8x+4 = 8*12+4 = 96+4 = 100
The three interior angles of the triangle are: 30, 100, 50
Note how 30+100+50 = 180 to help confirm the answer.

629 divided by the number c equals 17 what is c answer fast WILL MARK BRAINLY!!
Answers
Answer:
c=37
Step-by-step explanation:
The answer c is 37.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number
Here is is given that,
629 divided by the number c equals 17.
Here 629 is the dividend, c is the divisor and 17 is the quotient.
We have to find the value of the divisor.
Mathematically the given statement can be written as,
629 / c = 17
Multiplying both sides of the equation with c, we get,
629 = 17 c
Dividing both sides by 17,
c = 629 / 17
c = 37
Hence the value of c is 37.

Step-by-step explanation:
The y intercept is -4 as you can see in the graph. To find the slope look at the graph and find where it perfectly intercepts. It goes up one block and to the right three. So the slope is 1/3 . Since the line is going up to the top right it’s a positive slope.
The toll on a highway is based on the number of miles driven. If the toll on a 15-mile stretch of highway is $0.60, find the cost to drive a 80-mile stretch.
Answers
Answer:
$3.20
Step-by-step explanation:
We have
15-mile stretch = $0.60
80-mile stretch = x
Cross Multiply
15 × x = 80 × $0.60
x = 80 × $0.60/15
x = $3.20
Hence, the cost to drive a 80-mile stretch is $3.20
Jessica and her father are comparing their ages. At the current time, Jessica's father is 24 years older than her l. Three years from now, Jessica father will be five times her age at the point
Answers
Answer:
Jessica is currently 3 years old and her father is 27 years old.
Step-by-step explanation:
System of Equations
Let's call:
x = Jessica's age
y = Jessica's father's age.
There are two conditions:
1: Jessica's father is 24 years older than her or, equivalently:
y = x + 24
2: Three years from now, he will have five times her age.
Three years from now, Jessica will have x+3 years, and her father will have y+3 years, thus:
y + 3 = 5( x + 3 )
Substituting the first condition into the second:
x + 24 + 3 = 5( x + 3 )
Operating:
x + 27 = 5x + 15
Subtracting x and 15:
27 - 15 = 5x - x
12 = 4x
Solving:
x = 12 / 4 = 3
x = 3
y = 3 + 24 = 27
y = 27
Jessica is currently 3 years old and her father is 27 years old.

O x = ti and X=25
=+21/2
Answers
Answer: the answer is B
Step-by-step explanation:
The solutions of the equation X⁴-9x² + 8 = 0 is ±2√2 and ±1
How to solve equation using substitutionX⁴-9x² + 8 = 0
Let x² = y
Then the equation becomes y² - 9y + 8 = 0
This is in the form ax² + bx + c = 0
We can solve by using quadratic formula for finding roots
x = {-b ± √(b² - 4ac)} / 2a
where,
a = 1, b = -9, c = 8= {-(-9) ± √((-9)2 - 4(1)(8))} / 2(1)
= {9 ± √(81 - 32)} / 2
= {9 ± √49} / 2
= {9 ± 7}/2
= 16/2, 2/2
= 8, 1
y = 8,1
x = ±2√2, ±1

Basil, Oscar and Sue share 43 sweets.
Sue gets the largest share.
What is the smallest possible number of sweets Sue could get?
Answers
Answer:
Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.
Step-by-step explanation:
Basil, Oscar, and Sue share 43 sweets.
Sue gets the largest share.
Let us divide the 42 sweets by 3
42/3 = 14
It means 3 equal parts of 14 make the sum 4.
i.e. 14+14+14 = 42
Since Basil, Oscar and Sue share 43 sweets, which is 1 plus 42.
So, add that 1 to Sue. i.e. 1+14 = 15
so 15+14+14 = 43Thus, Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.

What is inequality?A collection of two or more inequalities in one or more variables is known as a system of inequalities. When there are multiple constraints on a problem's potential solutions and a range of potential solutions are needed, systems of inequalities are used. The maximum or minimum values of a situation with multiple constraints are frequently determined using a system of linear inequalities.
It is given that,the sum of a number and 9, divided by 4, is greater than or equal to -2
Suppose the number is n,
(n+9)/4≥-2
n+9≥-8
n≥-8-9
n≥-17
Thus, if the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.
