What is the reciprocal of 8 2/3

Answer:

2/6; 3/9

Step-by-step explanation:

Multiply both the numerator and the denominator by the exact same number to find equivalent fractions

For example, I will randomly choose to multiply both by 2

Example 1:

1 × 2 / 3 × 2

2/6

Now, I'll do 3

Example 2:

1 × 3 / 3 × 3

3/9

You can check your work by dividing both the numerator and the denominator by the original fraction (1/3) to see if you get the number 1

Example 1:

2/6 ÷ 1/3

Copy dot flip

2/6 × 3/1

2 × 3 / 6 × 1

6/6

1

Example 2:

3/9 ÷ 1/3

Copy dot flip

3/9 × 3/1

3 × 3 / 9 × 1

9/9

1

Answer:

Step-by-step explanation:

A(-10,-3), B(7,14)

slope of AB = (-3-14)/(-10-7) = 1

slope of perpendicular to AB = -1

equation of perpendicular through C(5,12):

y-12 = -(x-5)

y-12 = -x+5

x = -y+17

x-intercept is the value of x when y=0.

x-intercept = 17

(0,17) is a point on CD.

Answer:

[tex](-2,6)[/tex]

Step-by-step explanation:

Given

[tex]Elena = (10,-4)[/tex]

[tex]Midpoint = (4,1)[/tex]

Required

Determine the coordinates of Naya's

Midpoint is calculated as:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

In this case:

[tex](x_1,y_1) = (10,-4)[/tex]

[tex](x,y) = (4,1)[/tex]

So, we have:

[tex](4,1) = \frac{1}{2}(10+x_2,-4+y_2)[/tex]

Multiply through by 2

[tex]2 * (4,1) = \frac{1}{2}(10+x_2,-4+y_2) * 2[/tex]

[tex](8,2) = (10+x_2,-4+y_2)[/tex]

By comparison:

[tex]8 = 10 + x_2[/tex]

[tex]2 = -4 + y_2[/tex]

So:

[tex]8 = 10 + x_2[/tex]

[tex]x_2 = 8 - 10[/tex]

[tex]x_2 = -2[/tex]

[tex]2 = -4 + y_2[/tex]

[tex]y_2 =2+4[/tex]

[tex]y_2 =6[/tex]

So, the coordinate is: [tex](-2,6)[/tex]

Answer:

It really depends on how much percent of your overall grade tests count as. But, usually they count for about 60% of your grade (depending on what grade you are in). You have about 65% at the lowest and a 75% at the highest. But, I'm just going by what my school does, I don't know how your school grades tests.

Step-by-step explanation:

Answer:

yes.

honestly, I didn't really do all the math.

3 in 18 minutes, a little better than 3 in 20 minutes. that translates to 9 in an hour, with 6 minutes left over.

3 hours of that (3×9) is the 27. with 6 minutes per hour left over, for a total of 18 minutes.

the teacher has time to grade the tests, get a cup of coffee, and take a few minutes to wonder why she didn't go into an easier line if work.

Answer:

m = 1/2

Step-by-step explanation:

The given equation of line is :

2x – 4y = 9 ..(1)

We need to find the slope of the line. The general equation of a line is given by :

y = mx + c ..(2)

Where

m is the slope of line

Equation (1) can be rearranged as follow :

-4y = 9-2x

4y = -9+2x

or

4y = 2x-9

Divide both sides by 4.

[tex]\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})[/tex] ..(3)

Now comparing equation (2) and (3) we get :

[tex]m=\dfrac{1}{2}[/tex]

So, the slope of the line is 1/2.

Answer:5r2+2

Step-by-step explanation:

Distribute the Negative Sign:

=4r2−3r+2+−1(−r2−3r)

=4r2+−3r+2+−1(−r2)+−1(−3r)

=4r2+−3r+2+r2+3r

Combine Like Terms:

=4r2+−3r+2+r2+3r

=(4r2+r2)+(−3r+3r)+(2)

=5r2+2

Answer:

Step-by-step explanation:

1) Let x be the number of adults and y be the number of students

x + y = 8 --------------(I)

        y = 8 -x

7.25x + 5.50y = 52.75 ----------------(II)

Substitute y = 8 -x in equation (II)

7.25x + 5.5*(8 - x) = 52.75

7.25x + 5.5*8 - x*5.5 = 52.75

7.25x +  44 - 5.5x = 52.75

7.25x - 5.5x + 44 = 52.75

             1.75x + 44 = 52.75

                  1.75x    = 52.75 - 44

                       1.75x = 8.75

                           x = 8.75/1.75

x = 5

Plugin x = 5 in equation 1

y = 8 - 5

y = 3

2)  x = y + 24

x + y = 180   {Supplementary}

y + 24 + y = 180

2y + 24 = 180

      2y = 180 - 24

     2y =  156

        y = 156/2

y = 78

x = 78 + 24 = 102

Answer:

D

Step-by-step explanation:

took the test

The expression is equivalent to (n² - 7n + 12) is (n-4)/ (n+4).

The correct option is D.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

We have,

(n² - 7n + 12) / (n-3)(n+4)

So, Factorizing (n² - 7n + 12)  

= (n² -3n - 4n +12)

= n(n-3)- 4(n-3)

= (n-3)(n-4)

Then, (n² - 7n + 12) / (n-3)(n+4)

= (n-3)(n-4)/ (n-3)(n+4)

= (n-4)/ (n+4)

Answer:

90,45,45

Step-by-step explanation:

it a system of equations

say that x y and z are each angles of the triangle

that means that they add up to 180 so x+y+z=180

the question says that two of the angles in the triangle are equal so we can just say that x=y

and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z

x+y+z=180

x+y=z

x=y

we start with the first two equations:

since x+y=z then we can substitute z in for x+y in the first equation

z+z=180

2z=180

z=90

and since x=y then

x+x=z

2x=90

x=45

y=45

z=90

Answer:

x = 32

y = 16sqrt(5)

z = 8sqrt(5)

Step-by-step explanation:

x/16 = 16/8

x/16 = 2

x = 32

y^2 = 16^2 + 32^2

y^2 = 1280

y = 16sqrt(5)

z^2 = 8^2 + 16^2

z^2 = 320

z = 8sqrt(5)
