Carmen had
of a spool of yarn. She used
of her yarn for a project. What fraction of the spool was used for the project?
Write your answer in simplest form.
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
x+1/x-1-x-1/x+1=7/12
Given:
The equation is:
[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]
To find:
The value of x.
Solution:
Formulae used:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
[tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex](a-b)(a+b)=a^2-b^2[/tex]
We have,
[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]
Taking LCM, we get
[tex]\dfrac{(x+1)^2-(x^2-1)^2}{(x-1)(x+1)}=\dfrac{7}{12}[/tex]
[tex]\dfrac{x^2+2x+1-(x^2-2x+1)}{x^2-1^2}=\dfrac{7}{12}[/tex]
On cross multiplication, we get
[tex]12(x^2+2x+1-x^2+2x-1)=7(x^2-1)[/tex]
[tex]12(4x)=7x^2-7[/tex]
[tex]48x=7x^2-7[/tex]
[tex]0=7x^2-48x-7[/tex]
Splitting the middle term, we get
[tex]7x^2-49x+x-7=0[/tex]
[tex]7x(x-7)+1(x-7)=0[/tex]
[tex](7x+1)(x-7)=0[/tex]
[tex]x=-\dfrac{1}{7},7[/tex]
Therefore, the values of x are [tex]-\dfrac{1}{7}[/tex] and [tex]7[/tex].

-5 = 1/7a
Answer:
-35
Step-by-step explanation:
[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a

ans 4) More than 5 factors
Answer:
Exactly 3 factors
Step-by-step explanatin
The number 1001 is a composite number because 1001 can be divided by one, by itself and at least by 7, 11 and 13. A composite number is an integer that can be divided by at least another natural number, besides itself and 1, without leaving a remainder (divided exactly).
The factorization or decomposition of 1001 = 7•11•13. Notice that here, it is written in exponential form.
The prime factors of 1001 are 7, 11 and 13. It is the list of the integer's prime factors.
The number of prime factors of 1001 is 3.
Solve by using common denominators 2/1 divide 1/4
Answer:
8
Step-by-step explanation:
That'd be "2/1 divided by 1/4" and if we use common denominators we get:

The answer is 20
Help I don’t understand this
Answer:
Step-by-step explanation:
they are opposite angles, so we put them equal to each other.
25.
6a+10= 130
6a=120 a=20 so now we plug it in 6(20) +10= 130
26. 4a-4=2a+30
2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64
27. 6y+1=4y+9 2x-5=x+7
2y=8 x=2
y=4
now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9
Find the missing side of the angle.
Need help,==== thank you!!
Answer:x=square root(239)
Step-by-step explanation:
The way to solve this is via the Pythagorean theorem(a^2 + b^2 = c^2)
a= a leg
b= another leg
c= hypotenuse
16^2 = square root(17)^2 + x^2
256 = 17+ x^2
239 = x^2
x=square root(239)

The graph below is an example of which type of function? On a coordinate plane, a function decreases, has a point of inflection, and then continues to decrease. quadratic linear cubic square root
Answer: its cubic
Step-by-step explanation:
The graph below is an example of a cubic type of function. Option C is correct.
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
1. A parabola is the graph of a quadratic function. As a result, the presented graph is not a quadratic function graph.
2. A straight line is represented by a linear function. As a result, the presented graph is not a linear function graph.
3. A cubic function's end behavior is opposite at both ends. We can see that the presented graph satisfies these requirements.
4. A square root function's graph resembles a half parabola. As a result, it can't be the graph of the square root function.
The graph below is an example of a cubic type of function.
Hence,option C is correct.
