Answer:
-22/3 =x
Step-by-step explanation:
(4x-4) /(x+4) = 10
Multiply each side by (x+4)
(4x-4) /(x+4) * (x+4) = 10 * (x+4)
(4x-4) = 10 * (x+4)
Distribute
4x-4 = 10x+40
Subtract 4x from each side
4x-4-4x = 10-4x+40
-4 = 6x+40
subtract 40 from each side
-4 -40 = 6x+40-40
-44 = 6x
Divide each side by 6
-44/6 = -6x/6
-22/3 =x
Answer:
x = -22/3
Step-by-step explanation:
4x - 4 / x + 4 = 10
=> 4x - 4 = 10(x + 4)
=> 4x - 4 = 10x + 40
=> 4x - 10x = 40 + 4
=> -6x = 44
=> x = -44/6
=> x = -22/3

1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?
Answer:
\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
\(A = \frac{h_{b}+b}{2}\)
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
By using trigonometric relations we will see that the area is:
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

A cell phone provider will allow you to pay for a new phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, where y represents the total cost of the phone and x represents number of months, what would be the slope?
A) 0
B) 75
C) 25
D) 50
Answer:
C) 25
Step-by-step explanation:
The charge per month, 25, multiplies the number of months, x, and then is added to the initial fee.
The function is
y = 25x + 50
The slope is 25.
Answer: C) 25
Audrey weaved a blanket. The area of the blanket is 36x2 + 19x - 6 meters
while its length is 9x – 2 meters. Find the expression for the width of the blanket.
Answer:
The area of the floor plan is given by the expression 20x² - 4x - 16
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal to each other. Also all the angles of a rectangle measure 90 degrees each.
Area of a rectangle = length * breadth
Area of the floor plan = length * breadth
Area of the floor plan = (5x + 4) * (4x - 4)
Area of the floor plan = 20x² - 20x + 16x - 16
Area of the floor plan = 20x² - 4x - 16
The area of the floor plan is given by the expression 20x² - 4x - 16.
Answer:
the expression for the width is 4x + 3
Step-by-step explanation:
Area = base times width. Thus, we divide 9x - 2 into 36x^2 + 19x - 6 to find an expression for the width. Dividing 9x into 36x^2, we get 4x, which tells us that the first term of the quotient starts with 4x: (4x + ? )(9x - 2). Replacing the '?' with 3, we get:
(4x + 3)(9x - 2), which through multiplication becomess
36x^2 + 27x - 8x - 6, or 36x^2 + 19x - 6, which was the original dividend.
Thus the expression for the width is 4x + 3 (in meters).
Every day, Ed's orange juice stand uses 2/3 of a bag of oranges. How many days will 2 2/3 bags of oranges last?
Answer:
4 days
Step-by-step explanation:
2 2/3 ÷ 2/3
2 2/3 = \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{2}{3}\) = \(\frac{8}{3}\) (\(\frac{3}{3}\) is another name for 1)
\(\frac{8}{3}\) ÷ \(\frac{2}{3}\) = \(\frac{4}{1}\) = 4

Answer:
$7000
Step-by-step explanation:
This problem seems scary at first sight, but don't be intimidated. It is actually pretty simple.
The column of equations (starting with 0.1d) at the right of T(d) is a list of option based on d, the taxable income. If d is less than or equal to (≤) 9875, than the equation is T(d) = 0.1d.
It shows that Noam has 90000 dollars for d, or the taxable income, and Betty has 120000 dollars.
Now, let's find the equations by plugging in 90,000 for d first.
90,000 is greater than 85, 526 and less than 163,300 (85, 526 ≤ 90,000 ≤ 163300).
Then we plug in 120,000 dollar to find the corresponding equation.
120000 is greater than 85, 526 and less than 163, 300 (85, 526 ≤ 120,000 ≤ 163300).
So the chosen equation is:
T(d) = .24( d -85525) + 14605.5
Plug in the Noam's number for d
T(d) = .24(90,000 - 85, 525) + 14, 605.5
T(d) = .24(4475) + 14,605.5
T(d) = 1074 + 14,605.5
T(d) = 15, 679.5
Now Plug in Betty's number for d
T(d) = .24 (120,000 - 85, 525) +14, 605.5
T(d) = .24( 34475) + 14, 605.5
T(d) = 8274 + 14, 605.5
T(d) = 22, 879.5
We are finding how much more tax does Betty pay, so we subtract 15, 679.5 from 22, 879.5.
22, 879.5 - 15, 679.5 = 7200
Betty pays $7000 more tax than Noam does.

Step-by-step explanation:
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

someone seriously needs to teach me how to do slope
To solve -9 - 16m = 7, what steps would you use?
(divide by; multiply by; add; or subtract) 9
(divide by; multiply by; add; or subtract) -16
Answer:
add 9
divide by -16
Step-by-step explanation:
I would add nine to both sides, making it -16m=16.
Then, I would divide by -16 on both sides to isolate the m.

An American traveling in Japan wishes to exchange American money for Japanese money. If the exchange rate is $1 = 80 yen, then how many dollars will the traveler need to purchase 10,000yen?
Answer: $125
Step-by-step explanation:
1/80=x/10,000
10,000/80=125
Hope this helped!
Answer:125 yen
Step-by-step explanation:
Ratio and proportion
Ratio=1:80=x:10,000
x represents dollars which is unknown
1/80=x/10,000
Then you cross multiply
80x=10,000
80x/80=10,000/80
x=125
Therefore,$125 will give you 10,000yen

Answer:
1. The graph is non-proportional because it starts from (0, 2).
2. The slope of the line is 3.
3. y=3x+2
Step-by-step explanation:
The graph is non-proportional since it didn't start from the origin (0, 0). If the graph starts from the origin, then it's proportional.
To find the slope of the line, use this equation, \(m=\frac{y2-x2}{y1-x1}\) or \(\frac{rise}{run}\) to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.
\(m=\frac{5-2}{1-0} =\frac{3}{1} =3\) I chose (0, 2) and (1, 5) to find the slope
Once you find the slope, write the equation in y=mx+b form to find what b is with one of the points given.
\(2=3(0)+b\)
\(-0\) \(-0\)
----------------------
2 = b
Equation of the line: y=3x+2

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.
