Answer: x = -5
-------------------------------------------------------------------------------------------------------------
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(1−5x)+5(−8x−2)=−4x−8x
-------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the equation.
−5(1−5x)+5(−8x−2)=−4x−8x
(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)
−5+25x+−40x+−10=−4x+−8x
(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)
−15x+−15=−12x
−15x−15=−12x
-------------------------------------------------------------------------------------------------------------
Step 2: Add 12x to both sides.
−15x−15+12x=−12x+12x
−3x−15=0
-------------------------------------------------------------------------------------------------------------
Step 3: Add 15 to both sides.
−3x−15+15=0+15
−3x=15
-------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by -3.
−3x /−3 = 15/ −3
x=−5
-------------------------------------------------------------------------------------------------------------

Answer:
(x -3)/(x -1) and (x +2)/(x -3)
Step-by-step explanation:
If you want the product of two fractions to be a/b, then 'a' must be a factor in the numerator of one of them, and 'b' must be a factor in the denominator of one of them.
'a' and 'b' are already in the numerator and denominator of a/b, so we can choose the other fraction to be something that has a value of 1, such as c/c.
(a/b)(c/c) = (ac)/(bc) = a/b
The intermediate product (before we reduce the result) has a numerator of 'ac' and a denominator of 'bc'. We can split those into two parts however we like. For example, we can get the same result by multiplying ...
(a/c)(c/b) = (ac)/(bc) = a/b
So, a simple answer to your question could be ...
[tex]\left(\dfrac{x-3}{x-1}\right)\times\left(\dfrac{x+2}{x-3}\right)=\dfrac{x+2}{x-1}[/tex]
__
The idea is to multiply the given result by 1 in some form. That form can be as complicated as you like, and its factors can be grouped any way you like

What is the first step in constructing the angle bisector of angle A?
Answer:
D)
Step-by-step explanation:
from point A, draw an arc that intersects both sides of the angle
From point A, draw an arc that intersects both sides of the angles. Thus, the correct option is D.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
An angle bisector is a line or ray that divides an angle into two equal parts. The angle bisector divides the angle into two smaller angles that have the same measure.
Thus, the correct option is D.

Solve for X…..
help plzzz i’ll give u brainliest
Answer:
x = 34
Step-by-step explanation:
4x and 44 are adjacent angles on a straight line and sum to 180° , that is
4x + 44 = 180 ( subtract 44 from both sides )
4x = 136 ( divide both sides by 4 )
x = 34
Which is larger the diameter of a nucleus or the diameter of a protron?
Inside a nucleus are neutrons and protons, which occupy a space about 100,000 times smaller than the whole atom. In the pond example, a proton would measure about 1/50th inch (0.5 millimeters) in diameter—about the size of a pinpoint.
So the answer would be the diamter of a nucleus.
Using the equation x squared minus c equals 0 , what value of c has 9 and -9 as solutions.
9514 1404 393
Answer:
c = 81
Step-by-step explanation:
The equation x² -c = 0 can be factored as ...
(x -√c)(x +√c) = 0
which has roots ±√c.
The roots are given as ±9, so we have ...
±9 = ±√c
c = (±9)² = 81
The value c = 81 makes the equation have ±9 as solutions.
Help with 17,18,19,,20 and 21
Answer:
17. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
18. Zero slope means that the line is horizontal. Just like the line that makes the top of a “Z” is horizontal. No slope means that the line is vertical.
19. Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
20. Yes, they did because 2/6 is equivalent to 1/3.
21. A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

Answer:
the median in that numbers is 6
Step-by-step explanation
their are total 7 number which is odd
so the formula is
median = ( n + 1 /2 )^th term
now,
→ ( 7 + 1 / 2 )
→ 8/2
→ 4th term
therefore, 4th term is the median and 4th term is 6 itself.

Subtract how much more angle 1 is from the total. :
112 - 48 = 64
Divide by 2:
64/2 = 32
Angle 2 = 32 degrees
Answer:
measure of angle 2 is 32 degrees.
Step-by-step explanation:
I will refer to the measure of the angles as m1 and m2 (I don't have the angle symbol on my keyboard).
we are looking for measure of angle 2, so let's call m2 "x".
so,
m2 = (x)
m1 = (48 + m2) or m1 = (48 + x)
and we know that:
m1 + m2 = 112
so we substitute the values above into the equation.
m1 + m2 = 112
(48 + x) + (x) = 112
combine like terms:
42 + x + x = 112
42 + 2x = 112
subtract 42 from both sides, leaving us with
2x = 64
divide by 2, giving us
x = 32
remember that we are looking for m2, which is x, so m2 is 32 degrees. hope this helped! (:

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle
Answer:
x=7, so the smallest angle would be 44?
Step-by-step explanation:
Okay, so in a triangle, all the angles have to add up to 180°. So your equation would be 44 + (5x+20) + (9x+18) = 180
So in order to find the smallest angle, you have to find x, so let's simplify the equation.
Add the like terms (5x + 9x = 14x) and then the regular integers (44 + 20 + 18 = 82)
So now we have 14x + 82 = 180. Subtract 82 from both sides of the equation, and you will have 14x = 98.
Divide both sides by 14, and you will get x = 7.
Now plug this in to both equations, and see which one is the smallest.
9(7) + 18 = 63 + 18 = 81
5(7) + 20 = 35 + 20 = 55
I'm not sure whether or not your problem meant "find the smallest angle with a variable" or just the smallest angle in general, but I hope this helps.

pounds of cheese can Keisha get if she buys
part only Cheddar cheese? Only Swiss cheese? A
mixture of both cheeses? What linear equation
in standard form can she use to model the
situation
Answer:
if she has to buy from a mixture of both the cheeses then equation will become;
N x C + M x S = 30
Explanation:
Let C represents the value of cheddar cheese per pound
Let S represents the value of swiss cheese per pound.
Equation when she only buys cheddar cheese will be;
N x C = 30,
Here N is the number of pounds of cheddar cheese
Equation when she only buys swiss cheese will be;
M x S = 30,
Here M is the number of pounds of swiss cheese
Now if she has to buy from a mixture of both the cheeses then equation will become;
N x C + M x S = 30
