What is the difference of 7/8-1/3
Answers
Answer: 7/8 is bigger and 1/3 is smaller
Step-by-step explanation:
0.875 is the decimal version of 7/8 and 0.333333333... is the decimal verision of 1/3. The difference is that 7/8's is bigger. If you want to compare fraction-wise you have to make them have the same denominator by doing that you have to mulitpy 7/8's by 3 which is 21/24 and you have to do the same thing to 1/3 so you have to mulitpy 1/3 by 8 to get 24 which makes 1/3 into 8/24. So now you got 8/24 and 21/24. Which one is bigger? Yep, 21/24. Please give me brainliest. I do well explaining it.
The difference of the given fractions is 13/24.
What is subtraction of fractions?Subtracting fractions include the subtraction of two or more fractions with the same or different denominators. Like fractions can be subtracted directly but for unlike fractions we need to make the denominators same first and then subtract them.
Given that, 7/8-1/3.
LCM of the denominators 8 and 3 is 24.
Now, make the denominators same for both the fractions, that is
7/8 = 21/24 and 1/3 = 8/24
Thus, 7/8-1/3=21/24-8/24
= 13/24
Therefore, the difference of the fractions is 13/24.

Chris has just sold a home valued at $85,000. Her
normal commission for the homes that she sells
is 8%. Determine the amount that Chris will make
on the sale of the $85,000 home.
Answers
Answer:
Amount of Chris' commission = $6800
Step-by-step explanation:
Given that:
Value of the house sold by Chris = $85,000
Percent of Chris' commission = 8%
Amount of Chris' commission = 8% of 85000
Amount of commission = [tex]\frac{8}{100}*85000[/tex]
Commission = 0.08 * 85000
Commission = $6800
Hence,
Amount of Chris' commission = $6800

sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
Brand A:
$2.50 for 2
Brand B :
$3.90 for 3
Brand C:
$5.12 for 4
We calculate the unit price :

Brand B:
$3.90 / 3 = $1.30
Brand C:
$5.12 / 4 = $1.2
Write the equation of the line passing through the given point that is perpendicular to the
given line.
12. y = - 4x + 7: (4,2)
Answers
Answer:
The equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]
Step-by-step explanation:
Write the equation of the line passing through the given point that is perpendicular to the given line.
y = - 4x + 7: (4,2)
The equation of required line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept
Finding slope:
When two lines are perpendicular their slopes are opposite reciprocal of each other. [tex]m_1=-\frac{1}{m_2}[/tex]
So, slope of given line = -4 ( Comparing with [tex]y=mx+b[/tex] m = -4)
Now, slope of required line will be: m =1/4 (Opposite reciprocal)
Finding y-intercept
y-intercept can be found using m = 1/4 and point (4,2)
[tex]y=mx+b\\2=\frac{1}{4}(4)+b\\2=b[/tex]
So, we get b = 2
Now, Equation of line
Equation of line having slope m = 1/4 and y-intercept b = 2 is:
[tex]y=mx+b\\y=\frac{1}{4}x+2[/tex]
So, the equation of the line passing through the given point that is perpendicular to the given line y = - 4x + 7: (4,2) is [tex]\mathbf{y=\frac{1}{4}x+2 }[/tex]
Solve the equation:
[tex]\frac{21 - 4x}{9}[/tex] + [tex]\frac{8x + 15}{3}[/tex] = 2
Answers
Answer:
[tex]x = -\frac{12}{5}[/tex]
Step-by-step explanation:
To solve the equation, isolate x. Whatever you do to isolate x one on side, you must do to the other.
1) Multiply both sides by 9 to get rid of the fractions.
[tex]\frac{21-4x}{9} +\frac{8x+15}{3} = 2 \\21-4x + 3(8x + 15) =18 \\[/tex]
2) Distribute the 3 to 8x and 15. Then, combine like terms.
[tex]21-4x + 24x + 45 = 18 \\66 + 20x = 18[/tex]
3) Move the 66 to the other side, subtracting 18 by 66, then divide each side by 20 to finally isolate x.
[tex]20x = -48\\x = -\frac{48}{20} \\x =- \frac{12}{5}[/tex]
Thus, [tex]x = -\frac{12}{5}[/tex].

Oy=-3x + 1
0 3x - 4y = -4
0 4x - 3y = -3
Oy-2 =(-4)
Oy +2 = (x + 4)
Answers
Answer:
The equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex][tex]3x - 4y = -4[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the line
3x - 4y = 7
writing in the slope-intercept form
4y = 3x - 7
dividing both sides by 4
4y/4 = 3/4x - 7/4
y = 3/4x - 7/4
Now, comparing with the slope-intercept form of the line equation
y = 3/4x - 7/4
The slope of the line m = 3/4
We know that parallel lines have the same slopes.
Therefore, the slope of the parallel line is: 3/4
now we have,
The point (-4, -2)
The slope m of parallel line = 3/4
Given the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting (-4, -2) and m = 3/4 in the point-slope form of line equation
[tex]\:y-\left(-2\right)=\frac{3}{4}\left(x-\left(-4\right)\right)[/tex]
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Thus, the equation in the point-slope form of the line equation is:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Simplifying the equation
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex]
Subtract 3 from both sides
[tex]y+2-2=\frac{3}{4}\left(x+4\right)-2[/tex]
[tex]y=\frac{3}{4}x+1[/tex]
Multiplying the equation by 4
[tex]4y = 3x + 4[/tex]
[tex]3x - 4y = -4[/tex]
Therefore, the equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
[tex]y+2=\frac{3}{4}\left(x+4\right)[/tex][tex]3x - 4y = -4[/tex]The equations that represent the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) are: y + 2 = 3/4x + 3 and y = 3/4x + 1
What is the Equation of Parallel Lines?If two lines are parallel, the slope (m), in their equation in slope-intercept form (y = mx + b) would be the same.
Rewrite the equation, 3x - 4y = 7 in slope-intercept form
-4y = -3x + 7
y = -3y/-4 + 7/-4
y = 3/4y - 7/4
The slope (m) is 3/4, therefore, the slope of the line that is parallel to 3x - 4y = 7 and passes through (-4, -2) would be: m = 3/4.
Substitute (a, b) = (-4, -2) and m = 3/4 into y - b = m(x - a)
y -(-2) = 3/4(x - (-4))
y + 2 = 3/4(x + 4)
y + 2 = 3/4x + 3
y = 3/4x + 3 - 2
y = 3/4x + 1
The equations that represent the line are:
y + 2 = 3/4x + 3 and y = 3/4x + 1

Answer:
[tex]\displaystyle y=\frac{1}{3}x-6[/tex]
Step-by-step explanation:
Dilation of a Line
Given a line that passes through points A(-3,-4) and B(-6,-5). We'll apply a dilation with a scale factor of 2 centered at the origin by multiplying each coordinate by 2. The points map to:
A'(-6,-8) and B'(-12,-10)
Now we find the equation of the line passing through A' and B'.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Substituting:
[tex]\displaystyle y+8=\frac{-10+8}{-12+6}(x+6)[/tex]
[tex]\displaystyle y+8=\frac{-2}{-6}(x+6)[/tex]
[tex]\displaystyle y+8=\frac{1}{3}(x+6)[/tex]
Operating:
[tex]\displaystyle y=\frac{1}{3}x+\frac{1}{3}*6-8[/tex]
[tex]\displaystyle y=\frac{1}{3}x+2-8[/tex]

The Reeds are moving across the country. Mr. Reed leaves 5 hours before Mrs. Reed. If he averages 40mph and she averages 50mph, how many hours will it take Mrs. Reed to catch up to Mr. Reed?
Answers
Answer:
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
Step-by-step explanation:
Given that:
Mr. Reed leaves 5 hours early.
Speed of Mr. Reed = 40 mph
Distance covered in 5 hours = 40 * 5 = 200 miles
Let,
h be the number of hours and D be the total distance.
D = 40h + 200
Speed of Mrs. Reed = 50 mph
D = 50h
For catching up, both distances will be same
D = D
50h = 40h + 200
50h - 40h = 200
10h = 200
Dividing both sides by 10
[tex]\frac{10h}{10}=\frac{200}{10}\\h=20[/tex]
Therefore,
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
