Answer: B)-4
Step-by-step explanation:
The given equation: [tex]\dfrac{6}{x^2-9}-\dfrac{1}{x-3}=1[/tex]
Using identity: [tex]a^2-b^2=(a-b)(a+b)[/tex]
[tex]\dfrac{6}{(x-3)(x+3)}-\dfrac{1}{x-3}=1\\\\\Rightarrow\ \dfrac{6-(x+3)}{(x-3)(x+3)}=1\\\\\Rightarrow\ \dfrac{6-x-3}{(x-3)(x+3)}=1\\\\\Rightarrow\ 3-x=(x-3)(x+3)\\\\\Rightarrow\ (-1)(x-3)=(x-3)(x+3)\\\\\Rightarrow\ -1=x+3\\\\\Rightarrow\ x=-1-3=-4 \ \ \ [x\neq3][/tex]
Hence, the solution is : x=-4
The correct option is B.
A visual-effects model maker for a movie draws a spaceship using a ratio of 1 : 24. The drawing of the spaceship is 22 inches long. What is the length of the spaceship in the movie?
Group of answer choices
Answer:
Length of spaceship in movie = 528
Step-by-step explanation:
Given that:
Drawing ratio of spaceship = 1 : 24
It means that 1 inch on drawing equals 24 inches in movie
Drawing of spaceship = 22 inches
Length of spaceship in movie = x
As the relationship is proportional,
1 : 24 :: 22 : x
Product of mean = Product of extreme
24*22 = x
x = 528
Hence,
Length of spaceship in movie = 528

9514 1404 393
Answer:
b = 7c = 5Step-by-step explanation:
Opposite sides of a parallelogram have the same length, so ...
5b +5c = 60
5b +4c = 55
Subtracting the second equation from the first, we get ...
c = 5
Substituting that into the first equation, we have ...
5b +5·5 = 60
5b = 35 . . . . . . . subtract 25
b = 7 . . . . . . . . . . divide by 5
The values b = 7 and c = 5 will make this a parallelogram.

a student buys (x) fashion magazines and (y) sports magazines. Each fashion magazine costs $2.00 and each sports magazine costs $1.60. If the student buys a total of 8 magazines for $14.00, which equation best represents the situtation
Answer:
Step-by-step explanation:
the student buys a total of 8 magazines for $14.00
x+y = 8
x = 8-y
2x+1.6y = 14
2(8-y)+1.6y = 14
16-2y+1.6y = 14
16-0.4y = 14
0.4y =16-14 = 2
y = 2/0.4 = 5
x = 8-y = 3
The correct equation best represents the situation is,
⇒ x + y = 8
And, 2x + 1.60y = 14.00
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A student buys (x) fashion magazines and (y) sports magazines.
And, Each fashion magazine costs $2.00 and each sports magazine costs $1.60.
Here, The student buys a total of 8 magazines for $14.00.
Hence, We can formulate;
⇒ x + y = 8
And, 2x + 1.60y = 14.00
Thus, The correct equation best represents the situation is,
⇒ x + y = 8
And, 2x + 1.60y = 14.00

The value of the missing part of the triangle given above would be = 7.5. That is option A.
How to calculate the missing value of the given triangle?To calculate the missing length of the similar triangle, the formula listed below should be used.
That is;
a/a+b = c/c+d
where a = 8
b = 10
c = 6
d = ?
That is;
8/8+10 = 6/6+d
make d the subject of formula;
8(d+6) = 6(18)
8d +48 = 108
8d = 108-48
8d = 60

Divide 1 1/2 divided by 1/4 in simplest form
Answer:
6
Step-by-step explanation:
1 1/2 divided by 1/4. Firstly you simplify the mixed number 1 1/2 to an improper fraction to make the process easier. So if it is simplified it would be 3/2.
Now you follow the division process and then simply the answer and it would be 6.
Answer:
Answer is 6
Step-by-step explanation:
Change 1 1/2 into 3/2
Multiply by the reciprocal: 3/2 x 4/1
3/2 x 4/1 = 12/2
12 divided by 2 = 6

The total cost (c) in dollars of renting a car for n days is given by the inequality LaTeX: c\ge125+50nc ≥ 125 + 50 n. What is the maximum number of days for which a car could be rented if the total cost was $425?
Answer:
6 daysStep-by-step explanation:
Given the inequality expression of the total cost (c) in dollars of renting a car for n days as c ≥ 125 + 50n
To get the maximum number of days for which a car could be rented if the total cost was $425, substitute c = 425 into the expression and find n
425 ≥ 125 + 50n
Subtract 125 from both sides
425 - 125 ≥ 125 + 50n - 125
300≥ 50n
Divide both sides by 50
300/50≥50n/50
6 ≥n
Rearrange
n≤6
Hence the maximum number of days for which a car could be rented if the total cost was $425 is 6days

Solve the area formula for a circle, A = πr2, for r2.
r2 = Aπ
r2 = A – π
Answer:
The solution of r² is r² = [tex]\frac{A}{\pi }[/tex]
Step-by-step explanation:
To solve an equation for one of its variables, do that
Separate the term of this variable on one side and the other terms on the other sidesMake the coefficient of the variable equals1 (if it is not 1)Let us solve the question
∵ The formula of the area of the circle is A = π r²
∵ The subject is r² ⇒ The variable which we need to solve for it
→ By using the 1st step up divide both sides by π to move it from the right
side to the left side
∵ [tex]\frac{A}{\pi }[/tex] = [tex]\frac{\pi r^{2}}{\pi }[/tex]
∴ [tex]\frac{A}{\pi }[/tex] = r²
→ Switch the two sides
∴ r² = [tex]\frac{A}{\pi }[/tex]

[tex]x=29[/tex]
Step-by-step explanation:
The two pair of angles that are given values are supplementary, meaning they add up to [tex]180^{\circ}[/tex]. Therefore, we have the following equation:
[tex]2x-10+4x+16=180,\\6x+6=180,\\6x=174,\\x=\fbox{$29$}[/tex].
Answer:
[tex]\huge{ x=29° }[/tex]
Step-by-step explanation:
Here,
The two lines are parallel.
So,The angle (2x-10) and (4x+16) are corresponding. because these angles are the consecutive interior angles.
we know that,
Sum of corresponding angle =180°
According to the question,
[tex]\bold{(2x-10)+(4x+16)=180 }[/tex]
[tex]\bold{2x-10+4x+16=180 }[/tex]
[tex]\bold{ 6x+6=180 }[/tex]
[tex]\bold{6x=180-6 }[/tex]
[tex]\bold{ 6x=174 }[/tex]
[tex]\bold{ x=\dfrac{174}{6} }[/tex]
[tex]\bold{ x=29 }[/tex]
so,
value of x=29°
