7/8m + 9/10 - 2m - 3/5
Answer:
The simplified form is [tex]-\frac{9m}{8}+\frac{3}{10}[/tex]
Step-by-step explanation:
Consider the provided expression.
[tex]\frac{7}{8}m + \frac{9}{10} - 2m - \frac{3}{5}[/tex]
Now combine the like terms,
Like terms are the terms which contains same variables of same degree.
[tex]\frac{7}{8}m -2m + \frac{9}{10}-\frac{3}{5}[/tex]
The above expression can be written as:
[tex]\frac{7}{8}m -\frac{8}{8}\times 2m + \frac{9}{10}-\frac{2}{2}\frac{3}{5}[/tex]
[tex]\frac{7-16m}{8}+\frac{9-6}{10}[/tex]
[tex]-\frac{9m}{8}+\frac{3}{10}[/tex]
Hence, the simplified form is [tex]-\frac{9m}{8}+\frac{3}{10}[/tex]
Answer:
The simplified expression is - 7/8 m + 3/10

Using scale factor of 1 inch = 5 feet, the blueprint dimensions of bedroom that is 12 feet x 18?
Choices
A) 2.2 in. X 3.3 in.
B) 2.4 in. X 3.6 in.
C) 2.8 in. X 4.2 in.
D) 2.9 in. X 5.0 in.
The blueprint dimensions for a bedroom that is 12 feet by 18 feet using a scale factor of 1 inch = 5 feet are 2.4 inches by 3.6 inches, which is choice B.
To find the blueprint dimensions of a bedroom that is 12 feet by 18 feet using a scale factor of 1 inch = 5 feet, we need to convert the actual dimensions to inches on the blueprint. For the length:
12 feet / 5 feet per inch = 2.4 inches
And for the width:
18 feet / 5 feet per inch = 3.6 inches
Therefore, the dimensions on the blueprint would be 2.4 inches by 3.6 inches, which corresponds to choice B.

Answer:
In functions, there can be more than one of the same output, but there cant be more than one of the same input.
Step-by-step explanation:
Let's look at table A.
Input Output
4 3
3 2
3 1
We have two 3's for our input.
Let's take a different approach to this if you don't understand.
Let's imagine we have a vending machine.
If you press the number 2 you get Doritos
If you press the number 4 you get Sprite
Though if you press the number 3 you could either get Cashews or Cheetos. If you paid for the Cheetos and you get Cashews, that wouldn't be good; Its like a guessing game.
So, therefore Table A is NOT correct, as two of our input's are the same number.
Now let's look at Table B
Input Output
1 3
3 5
5 7
All of our input's are different, which is good. Let's imagine the vending machine again.
Pressing number 1 gives us Doritos
Pressing number 3 gives us Barbecue Chips
Pressing number 5 gives us Kettle Chips.
We get what we pay for, which means, in this equation, if you input is number 1, we will have number 3 as our output, ect.
This table IS correct.
I think you can apply this procedure to the other two tables to determine which one is right :)

josh's web site had 805,289 visitors. Diego's site had 784,976 visitors. How many more visitors did josh's sit have than Diego's. Estimate to check your answer.
Josh's site had 20,313 more visitors than Diego's site. To estimate, we round the number of visitors to each site to the nearest thousand and subtract, revealing an approximate difference of 20,000 visitors, which is close to the exact count.
To find out how many more visitors Josh's site had than Diego's, we subtract the number of visitors to Diego's site from the number of visitors to Josh's site.
Josh's site had 805,289 visitors and Diego's site had 784,976 visitors. So we calculate:
805,289 - 784,976 = 20,313
Josh's site had 20,313 more visitors than Diego's site.
Estimate:
To estimate, we can round the numbers to the nearest thousand:
Josh's site: Approximately 805,000 visitors
Diego's site: Approximately 785,000 visitors
Now we subtract:
805,000 - 785,000 = 20,000
The estimate shows that Josh's site had about 20,000 more visitors than Diego's, which is close to the exact difference of 20,313 visitors.

A line passes through (8,-1) and is perpendicular to y=2x-9. What is the equation of the line in point-slope form?
The equation of the line in point-slope form is y = -1/2x +3.
What is the slope of a line?A line's slope is defined as the ratio of the change in the y coordinates to the change in the x coordinates.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Therefore, the relationship between the change in the y-coordinate and the change in the x-coordinate.
Given coordinates (8, -1)
and the equation of a line is y = mx + c
given equation = y = 2x - 9
comparing from the equation of line we get m = 2
but the line passes from (8, -1) is perpendicular to a given line,
so the value for slope(m) for perpendicular is inverse of the negative of the slope of a given line,
so m = -1/2
and equation is (y - y₁) = m(x - x₁)
where y₁ = -1 and x₁ = 8
substitute the values
y - (-1) = -1/2(x - 8)
y + 1 = -1/2(x - 8)
y = -1/2x +4 -1
y = -1/2x +3
Hence the equation of a line is y = -1/2x +3.

Rita sprinted 77 feet in 10 seconds. how many miles per hour is this
Final answer:
Rita sprinted 77 feet in 10 seconds. Her speed is approximately 5.25 miles per hour.
Explanation:
To convert the distance covered by Rita from feet to miles, we need to divide the distance by the number of feet in a mile:
77 feet ÷ 5280 feet/mile = 0.0145833 miles
To convert the time from seconds to hours, we need to divide the time by the number of seconds in an hour:
10 seconds ÷ 3600 seconds/hour = 0.00277778 hours
To calculate the speed in miles per hour, we divide the distance by the time:
Speed = Distance ÷ Time = 0.0145833 miles ÷ 0.00277778 hours ≈ 5.25 miles per hour

$1725 couch with a 15% markup
To find the final price of the couch with a 15% markup, we add the markup to the original price of the couch.
Explanation:In this question, we are given a couch priced at $1725 with a 15% markup. To find the final price, we need to add the markup to the original price of the couch.
Markup = 15% of $1725 = (15/100) * $1725 = $258.75
Final price = Original price + Markup = $1725 + $258.75 = $1983.75

A rectangle has an area of 20 square feet and a length of 6 feet. What is its width? show me how you got the answer.
3 1/3 is the width of the given rectangle.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
We can use the formula for the area of a rectangle, which is:
area = length x width
We are given the area as 20 square feet and the length as 6 feet. We can plug these values into the formula and solve for the width:
20 = 6 x width
Dividing both sides by 6, we get:
width = 20/6
Simplifying this fraction, we get:
width = 3 1/3 feet
Therefore, the width of the rectangle is 3 1/3 feet.

Final answer:
To calculate the width of a rectangle when the area is 20 square feet and the length is 6 feet, you divide the area by the length to get the width, which is 3⅓ feet.
Explanation:
To find the width of a rectangle when the area and the length are given, you can use the formula for the area of a rectangle, which is Area = length × width. In this case, we are given the area (20 square feet) and length (6 feet), so we set up the equation:
20 square feet = 6 feet × width
To solve for the width, we divide both sides of the equation by the length (6 feet):
Width = 20 square feet ÷ 6 feet
Width = 3.3333 feet or 3⅓ feet
Therefore, the width of the rectangle is 3⅓ feet.
