(+4) + (-13) = solve.

Answer:

4 over 3 or 4 : 3.

Step-by-step explanation:

See the diagram attached.

Now, The ratio of X's to O's is 12 : 9.

Now, we have to determine another ration for X's to O's.

The image will help us to do that.

There are 12 numbers of X and that can be broken into 3 sets of X with 4 X in each set. Hence, 12 = 3 × 4

Again, there are 9 numbers of O and that can be broken into 3 sets of O with 3 O in each set. Hence, 9 = 3 × 3

Therefore, the ratio of X's to O's is 12 : 9 ≡ (3 × 4) : (3 × 3) ≡ 4 : 3

{Cancelling 3 from each term} (Answer)

Answer:

The answer is 4 over 3.

Step-by-step explanation:

if you look at the image all you have to do is count the X's on the top, and that's the top of your fraction, then count the bottom number, that's the bottom of your fraction.

4 on the top three on the bottom so your fraction/ratio is 4 over 3!

hope this helped!!!

the factored form of the expression [tex]\(3x^2 + 7x - 6\) is \((3x - 2)(x + 3)\).[/tex]

To factor the expression [tex]\(3x^2 + 7x - 6\),[/tex] we need to find two numbers that multiply to give [tex]\(3 \times (-6) = -18\)[/tex] and add to give the middle coefficient, (7)

The two numbers that meet these criteria are [tex]\(9\) and \(-2\).[/tex]

Now, we can rewrite the middle term \(7x\) as the sum of these two terms:

[tex]\[3x^2 + 9x - 2x - 6\][/tex]

Next, we group the terms and factor by grouping:

[tex]\[3x(x + 3) - 2(x + 3)\][/tex]

Now, we can factor out the common factor [tex]\(x + 3\):[/tex]

[tex]\[(3x - 2)(x + 3)\][/tex]

So, the factored form of the expression [tex]\(3x^2 + 7x - 6\) is \((3x - 2)(x + 3)\).[/tex]

Answer: [tex]\frac{11}{12}[/tex]

Step-by-step explanation:

Since we are looking for the total fraction completed , all we need do is to add the fraction completed last month and the fraction completed this week , that is

[tex]\frac{2}{3}[/tex] + [tex]\frac{1}{4}[/tex]

The L.C.M is 12 , so we have

[tex]\frac{2}{3}[/tex] + [tex]\frac{1}{4}[/tex] =[tex]\frac{8 +3}{12}[/tex]

= [tex]\frac{11}{12}[/tex]

Therefore 11/12 is completed

Answer:

You completed 11/12 of your project.

Step-by-step explanation:

Change into a common denominator: 2/3 = 8/12 and 1/4 = 3/12

8/12 + 3/12 = 11/12

Answer:

The number of roots for  equation [tex]5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex] is 4 .

Step-by-step explanation:

Here, the given function polynomial is :

[tex]P(x) : 5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex]

The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity).

Now here, the degree if the polynomial is 4 (highest power of variable x).

So, according to the Fundamental Theorem, the given polynomial can have AT MOST 4 roots, counting Multiplicity.

Hence,  the number of roots for  equation [tex]5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex] is 4 .

The equation 7 - x = 3 is best modeled by the situation where the original price of a book at $7 is lowered by an amount of $4 to reach the final price of $3.

The given equation 7 - x = 3 can be used to model a situation where the price of a book, originally $7, is reduced by some amount to $3. After solving the equation by subtracting 7 from both sides and then multiplying by -1, we get x = 4. This means the amount reduced from the original price is $4, which is consistent with a price reduction scenario: the book's original price was $7, and it was reduced by $4, bringing the final price to $3.

Step-by-step explanation:

7+7+7=21*7=147

Answer:

Explanation:

This question requires that you find the value of    [tex]a[/tex]    given that:

That is you have to solve the equation for a.

1. Rewrite the equation in form of fractions, convert the mixed number into an improper fraction, and convert the decimal number into fraction too.

[tex]2\frac{1}{7}:(15a)=(5/14)/(0.8)\\ \\ \frac{2+\frac{1}{7} }{15a} =\frac{5/14}{8/10}\\ \\\frac{(14+1)/7}{15a} =\frac{5\times 10}{8\times 14}\\ \\ \frac{15}{7\times 15a} =\frac{50}{112}[/tex]

2. Cross multiply to leave a alone:

[tex]a=15\times 112/(7\times 15\times 50)\\ \\a=1680/5250\\ \\a=0.32[/tex]

the solution is y = 7

Step-by-step explanation:

Given equation is

[tex]8+5y=(8y-6)-7[/tex]

The equation has to be solved for y

So,

Opening brackets first

[tex]8+5y=8y-6-7\\8+5y=8y-13[/tex]

Subtracting 8 from both sides

[tex]8+5y-8=8y-13-8\\5y=8y-21[/tex]

subtracting 8y from both sides

[tex]5y-8y = 8y-21-8y\\-3y=-21y[/tex]

Dividing both sides by -3

[tex]\frac{-3y}{-3} = \frac{-21}{-3}\\y = 7[/tex]

so,

the solution is y = 7

Answer:

The number of movies that can can fit on shelf of 5 feet is 9 .

Step-by-step explanation:

Given as :

The measure of each movies case = 7 inches wide

Let the number of movies for 5 feet wide = n

Now ,

∵ 1 feet = 12 inches

∴ 5 feet = 12 × 5 = 60 inches

I.e 5 feet = 60 inches

Now, Again

For 7 inches wide  , the number of movies = 1

So, for 1 inch wide case, the number of movies = [tex]\frac{1}{7}[/tex]

∴ For 60 inches wide case, the number of movies = [tex]\frac{1}{7}[/tex] × 60

I.e For 60 inches wide case, the number of movies = 8.57 ≈ 9

Hence the number of movies that can can fit on shelf of 5 feet is 9 . Answer

The slope-intercept form for given equation is:

[tex]y = -\frac{7}{8}x-6[/tex]

Step-by-step explanation:

Given equation is:

[tex]7x+8y = -48[/tex]

The given equation is in standard form. The slope-intercept form is:

[tex]y =mx+b[/tex]

Ao, to convert the given equation to slope-intercept form

Subtracting 7x from both sides

[tex]7x-7x+8y = -7x-48\\8y = -7x-48[/tex]

Dividing both sides by 8

[tex]\frac{8y}{8} = \frac{-7x-48}{8}\\y=-\frac{7}{8}x-\frac{48}{8}\\y = -\frac{7}{8}x-6[/tex]

The slope-intercept form for given equation is:

[tex]y = -\frac{7}{8}x-6[/tex]

Answer:

16

Step-by-step explanation:

48/3=16

Answer:

(4, 0)

Step-by-step explanation:

To use elimination, you need to make the coefficients of one of the variables the same in each equation.  For example, we can multiply the first equation by 2 and the second equation by 3:

6x + 4y = 24

6x + 15y = 24

Now we can subtract the equations, eliminating the x terms.

(6x + 15y) − (6x + 4y) = 24 − 24

11y = 0

y = 0

Now plug into either equation to find x.

3x + 2y = 12

3x + 0 = 12

x = 4

Answer:

6 people

Step-by-step explanation:

Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.

Note: It was not said that each room has space for 6 people but the hotel has space for 6 people

Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.

Final answer:

The student's request for fractions between -8/10 and -4/5 cannot be fulfilled because these two fractions are equivalent. To provide a meaningful answer, it's assumed that the intended question is to find fractions between -8/10 and -9/10, for which examples are given.

Explanation:

The question is asking for five fractions that are between -8/10 and -4/5. First, notice that -8/10 is equivalent to -4/5, so we actually need to find fractions between two identical values. This is not possible as no fractions can exist between two identical numbers. However, assuming that the question intends for incremental fractions between two different numerators with the same denominator, we could consider finding fractions between -8/10 and -9/10, or between -7/10 and -8/10.

For simplicity, let's find five fractions between -8/10 and -9/10:

-17/20

-18/20

-19/20

-39/40

-79/80

These fractions are chosen because they simplify to values that lie between -8/10 and -9/10 when reduced to the same denominator.

Answer:

m=29/14

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-(-20))/(9-(-5))

m=(9+20)/(9+5)

m=29/14

The required slope is [tex]\dfrac{29}{14}[/tex].

Given:

The two points are [tex](-5,-20)[/tex] and [tex](9,9)[/tex].

To find:

The slope of the line.

Explanation:

Slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Using the slope formula, we get

[tex]m=\dfrac{9-(-20)}{9-(-5)}[/tex]

[tex]m=\dfrac{9+20}{9+5}[/tex]

[tex]m=\dfrac{29}{14}[/tex]

Therefore, the slope of the line is [tex]\dfrac{29}{14}[/tex].
