you are given a fraction in simplest form. the numerator is not zero.when you write the fraction as a decimal,it is a repeating decimal. which numbers from 1 to 10 could be the denominator
Answer:
3, 6, 7, 9
Step-by-step explanation:
We can take a look at each value from 1 to 10
We see that for 3, 6, 7, and 9 the decimal repeats forever for some numerators. For example, 1/3 repeats forever, 4/6 repeats forever, 5/7 repeats forever, 1/9 repeats forever.
Find the value of each variable.

Find the GCF of the set of numbers.
8 and 12
Enter the correct answer in the box.
Answer:
4
Step-by-step explanation:
prime factorization of 8 is 2x2x2
prime factorization of 12 is 2x2x3
2x2 are the only common factors, therefore GCF is 4
Answer:
4 is the GCF

The answer for the first question is A
The answer the second question is D
Step-by-step explanation:
so, let's look at the options.
A. (x+3)/x = 3
that hurts already by just looking at it.
but let's check anyway :
x + 3 = 3x
3 = 2x
and that is only true for one value of x (3/2), but not in general.
so, this is wrong.
B. (x²+5)/5 = x² + 1
x² + 5 = 5x² + 5
x² = 5x²
that is only true for one value of x (0), but not in general.
so, this is wrong.
C. (2x+7)/(2x+9) = 7/9
9(2x+7) = 7(2x+9)
18x + 63 = 14x + 63
4x = 0
that is only true for one value of x (0), but not in general.
so, this is wrong.
D. (-5x - 10)/(x+2) = -5
-5x - 10 = -5(x + 2) = -5x - 10
now this is true in all cases, so this is correct.
make simple :
(a² - 4a + 4) / (a² - 4)
with a little bit of experience you see right away that
a² - 4a + 4 = (a - 2)²
as we know from the generic squaring
(a - b)² = a² - 2ab + b² : a perfect fit.
and
(a² - 4) = (a + 2)(a - 2)
as we know from the generic factor multiplying
(a+b)(a-b) = a² + ab - ab - b² = a² - b² : a perfect fit.
so, the given expression is actually
(a - 2)² / ((a - 2)(a + 2)) = ((a-2)(a-2)) / ((a-2)(a+2))
and so, after eliminating one (a-2) term in the numerator and in the denominator the following remains :
(a - 2) / (a + 2)
and that is answer A

To the nearest percent, the probability that a given

Answer:
Step-by-step explanation:
probability of an event: number of events that satisfy the criteria/ total number of events
number of events that satisfy the criteria (in this case the number of families with three people)= 200
total number of events= 1000
200/1000= 20%

Solve the equation for all real solutions in simplest form.
3x2 - 12x + 11 = x
Answer:
(13 + or - (sign) square root(37)) / 6
Step-by-step explanation:
First search up the quadratic formula which is
x = (- b + or - square root(b^2 - 4ac)) / 2a
and to find a, b, and c you need this formula
ax^2 + bx + c = 0 (btw this is the safest solution to finding your answer with a number in-front of a quadratic equation.)
Math:
a = 3, b = -13, c = 11
b = -13, because of the x on the other end of the equation as the equation above "ax^2 + bx + c = 0" you need the zero to proceed to this next step.
Side Note: You only take the number and not the variable, variables are x, y, w, z, or etc.
(- (- 13) + or - square root((-13)^2 - 4(3)(11) ) ) / 2 * 3
13 + or - square root(37) / 6

Find the value of x for both
Answer:
x = 18 and x = 30
Step-by-step explanation:
The 3 angles lie on a straight line and sum to 180° , that is
90 + x + 4x = 180
90 + 5x = 180 ( subtract 90 from both sides )
5x = 90 ( divide both sides by 5 )
x = 18
-------------------------------------
The 2 angles are corresponding and congruent , then
x = [tex]\frac{1}{2}[/tex] x + 15 ( multiply through by 2 to clear the fraction )
2x = x + 30 ( subtract x from both sides )
x = 30
Answer:
1. x=18 2. x=30
Step-by-step explanation:
For 1. the equation would be x+4x =90 as it is a 90 degree angle
So 5x=90 then x = 18
For 2. The 2 angles are the same so we set them equal to each other
x=1/2x+15
2x=x+30
x=30

Yara is trying to find the best price for 8 notebooks.
If 2 notebooks cost $14.00 at Barnyard Books, and 5 notebooks cost $20.00 at The Bookworm, how many dollars will Yara save if she buys 8 notebooks from The Bookworm instead of Barnyard Books?
Answer:
Yara will save $24.00 if she buys 8 notebooks from bookworm instead of barnyard books.
Step-by-step explanation:
if 2 notebooks = $14.00, then, 14 ÷ 2 = $7.00
Therefore, 1 notebook at Barnyard book is $7.00
She bought 8, so 8×7 = $ 56.00
> She will spend $56.00 at Barnyard book
while at bookworm, 5 notebooks cost $20.00
> 20 ÷ 5 = $4.00
Therefore, 1 notebook at bookworm cost $4.00
She bought 8, so 8×4 = $32.00
> She will spend $32.00
Subtract the total amount that she'll spend on both stores
$ 56.00 - $ 32.00 = $ 24.00
Therefore, Yara will save $24.00 if she buys 8 notebooks from bookworm instead of barnyard books
Find the value of x and angle AKB
I will give brainiest if you answer it and give a explanation.
Answer:
x = 35
Step-by-step explanation:
The angle marked 125° is angle DPE. The (vertical) angle formed from the rays opposite PD and PE is angle BPA. That angle is divided into two parts by ray PC. One of those parts is angle CPA, shown as 90°. The other part is angle CPB, shown as x°. This means ...
angle DPE = angle BPA . . . . vertical angles have the same measure
125° = 90° +x°
35 = x . . . . . . . . . . divide by °, subtract 90

Answer:
x = 1/2 or x = 2/3
Step-by-step explanation:
6x^2 = 7x - 2
=> 6x^2 - 7x + 2 = 0
=> 6x^2 - 3x - 4x + 2 = 0
=> 3x (2x - 1) -2 (2x - 1) = 0
=> (2x - 1) (3x - 2) = 0
2x - 1 = 0
=> 2x = 1
=> x = 1/2
or
3x - 2 = 0
=> 3x = 2
=> x = 2/3
Hopefully this helps!!
Answer:
x = [tex]\frac{2}{3}[/tex] , x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
6x² = 7x - 2 ( subtract 7x - 2 from both sides )
6x² - 7x + 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × 2 = 12 and sum = - 7
The factors are - 3 and - 4
Use these factors to split the x- term
6x² - 3x - 4x + 2 = 0 ( factor the first/second and third/fourth terms )
3x(2x - 1) - 2(2x - 1) = 0 ← factor out (2x - 1) from each term
(2x - 1)(3x - 2) = 0
Equate each factor to zero and solve for x
3x - 2 = 0 ⇒ 3x = 2 ⇒ x = [tex]\frac{2}{3}[/tex]
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
