Answer:
x=112
Step-by-step explanation:
First, let's get all of the fractions to a common denominator.
Based on the numbers given (8,56, and 7), let's make all of the denominators be 56
for [tex]\frac{-7}{8} x[/tex], multiply the numerator and denominator by 7.
[tex]\frac{-7x}{8}[/tex]×[tex]\frac{7}{7}[/tex]= [tex]\frac{-49}{56} x[/tex]
we can leave [tex]\frac{-5}{56}x[/tex] as it is
and for [tex]\frac{1}{7} x[/tex], we cam multiply the numerator and denominator by 8
[tex]\frac{1x}{7}[/tex]×[tex]\frac{8}{8}[/tex]=[tex]\frac{8x}{56}[/tex]
Here's the equation now:
[tex]\frac{-49x}{56}[/tex]-[tex]\frac{5x}{56}[/tex]+[tex]\frac{8x}{56}[/tex]=-92
now simlify the fractions
numerators:
-49x-5x+8x=-46x
here's the fraction now:
[tex]\frac{-46x}{56}[/tex]=-92
We can simplify the fraction by 2 so it's [tex]\frac{-23x}{28}[/tex]
[tex]\frac{-23x}{28}[/tex]=-92
now multiply both sides by [tex]\frac{28}{-23}[/tex], which is the reciprocal of [tex]\frac{-23}{28}[/tex] (to isolate the variable)
[tex]\frac{28}{-23}[/tex]×[tex]\frac{-23x}{28}[/tex]=-92×[tex]\frac{28}{-23}[/tex]
[tex]\frac{-92*28}{-23}[/tex]
x=112
Hope this helps!
Answer:
x = 112
Step-by-step explanation:
The common denominator is 56 because 8*7 is 56
[tex]-\frac{7*7*x}{8*7} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\-\frac{49*x}{56} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\\frac{-46*x}{56}=-92[/tex]
Multiply both sides by 56
-46*x = -92 * 56
-46*x = -5152
Divide by - 46
x = -5152/-46
x = 112

Write the equation for the perpendicular bisector of a segment that has endpoints (1, –4) and (3, 2).
Question 3 options:
A)
y = –3x – 1
B)
y = –3x + 5
C)
y = 3x + 5
D)
y = –1∕3x – 1∕3
Answer:
D. The m of the segment is 3, perpendicular slope is -1/3 bc their slope product is -1.
The equation of the perpendicular bisector of the segment with endpoints (1, -4) and (3, 2) is y = (-1/3)x - 1/3. The correct option is D.
How to calculate the equation of the line?To find the equation of the perpendicular bisector of a segment, we need to first find the midpoint of the segment.
The midpoint of the segment with endpoints (1, -4) and (3, 2) is:
[tex](\dfrac{(1+3)}{2} , \dfrac{(-4+2)}{2}) = (2, -1)[/tex]
Now we need to find the slope of the line passing through the two endpoints, which is:
[tex]m = \dfrac{(2 - (-4))} { (3 - 1)} = 3[/tex]
The slope of the perpendicular bisector will be the negative reciprocal of the slope of the segment. So the slope of the perpendicular bisector is:
m = -1/3
Finally, we can use the point-slope form of a line to find the equation of the perpendicular bisector, using the midpoint we found:
y - (-1) = (-1/3)(x - 2)
y + 1 = (-1/3)x + 2/3
y = (-1/3)x + 2/3 - 1
y = (-1/3)x - 1/3
Therefore, the equation of the perpendicular bisector of the segment with endpoints (1, -4) and (3, 2) is y = (-1/3)x - 1/3.

which signs do you have to fill in between the numbers to make this a true equation?
2802 1811 123 441 3633 ⅓ 32² 205
Answer:
Multiplication signs are filled in between the numbers to make it a true equation.
Step-by-step explanation:
In mathematics, a true equation occurs when the values on both sides of the equal sign (i.e. =) are the same. For example, 2 + 2 = 4 is a true equation; and 3 * 2 = 6 is a true equation.
For this question, multiplication signs are filled in between the numbers to make it a true equation as follows:
2802 * 1811 * 123 * 441 * 3633 * ⅓ * 32² * 205 = 69,972,637,305,761,000,000

Which half of the unit circle satisfies the trigonometric inequality cos Ø >0? Assume that ø is the angle made by the
positive x-axis and a ray from the origin.
O the top half
O the bottom half
O the right half
O the left half
Answer:
the right half
Step-by-step explanation:
We know that cosine is a pair function.
This means that:
Cos(a) = Cos( -a)
We also know that:
Cos(pi) = 0
then:
Cos(-pi) = 0
pi and -pi are located in the y-axis, so from this we can know that the cosine function will be always positive on the right side, or in the left side, we can discard the other two options.
Now, we also know that cos(0) = 1.
And:
-pi < 0 < pi
So the two zeros are at the y-axis, and we know that cos(0) is positive (the angle 0 would be on the positive side of the x-axis, at the right), then all the right side must be positive.
Then the correct option is:
the right half
Answer:
C - The right half

A Jewelry artist is selling at an fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.00. The artist is selling the necklaces at $12 each.
The inequality 12n>145+4n represents the situation in which the artist a profit.
Answer:
a) Since the income is more than the cost, she makes a profit.
b) To make profits, she must sell at least 17 necklaces
Step-by-step explanation:
Inequalities
The costs of selling jewelry at a fair are $135 to rent a booth and $4 for each necklace. The cost function is:
C(n) = 135 + 4n
Where n is the number of necklaces she sells at the fair. She sells each necklace at $12 each, thus the income function is:
R(n) = 12n
a) If she sells n=17 necklaces, it will cost:
C(17) = 135 + 4*17 = 203
And the income is:
R(17) = 12*17= 204
Since the income is more than the cost, she makes a profit.
b) To make a profit R(n) > C(n), thus:
12n > 135 + 4n
Subtracting 4n:
8n > 135
n > 135/8
n > 16.875
Thus, to make profits, she must sell at least 17 necklaces
Van purchased a DVD player on sale. The original selling price was $175.80. The sale price was $150.65. Find the percent markdown.
Answer:
14%
Step-by-step explanation:
In this question, we have to find the percent markdown of the cost of the DVD player.
We know that the original price was $175.80, and now it is $150.65
To find the markdown, lets set this up as a proportion:
[tex]\frac{\$down}{original\$}=\frac{\%down}{100\%}[/tex]
First, lets find how much money was downed due to the sale. Do this by subtracting the sale cost from the original.
175.80 - 150.65 = $25.15
Since we now know our markdown cost, we can plug in the information to our proportion:
[tex]\frac{25.15}{175.80}=\frac{x}{100}[/tex]
Since we're solving for the percent markdown, we will replace the %down with an x, since we will be solving for x.
Solve for x:
[tex]\frac{25.15}{175.80}=\frac{x}{100}[/tex]
Cross multiply.
[tex]175.80x=2,515[/tex]
Divide both sides by 175.80
[tex]x=14.30602[/tex]
When you round the decimal to the nearest whole, you would get a markup of 14%
