Answer:

6 23/24

Step-by-step explanation:

First, find the least common factor of 8 and 12, the denominators.

8 16 24

12 24

24, is now the current denominnator,

8x 3 = 24

Now you go do it to the numerator, 3 x 3 = 9

9/24 + ?

Now, 12 x 2 = 24, do it to the numerator, 7 x 2 = 14

4 9/24 + 2 14/24

Now add the front numbers to make 6, than add the numerators and keep the denominator.

6 23/24, since you can not simplify this fraction, this is the answer.

Answer:

Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.

Step-by-step explanation:

Hope I helped.It's just a reminder of helpful things for means!

Answer:

59

Step-by-step explanation:

Suppose a, b, c, d, e and f represent the 6 numbers.  

Then, [tex]\frac{a + b + c + d + e + f}{6} = 14\\[/tex]

(1)         a + b + c + d + e + f = 84

Let's remove f

then [tex]\frac{a + b + c + d + e}{5} = 5[/tex]

(2)        a + b + c + d +e = 25

Substitute 25 in for  a + b + c + d +e in equation (1)

We have 25 + f = 84

                       f  = 59

Answer:

(-5, 3)

Step-by-step explanation:

Let O(x, y) be the centroid of the triangle.

The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.

The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.

For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:

[tex]x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3[/tex]

The centroid is at (-5, 3)

Answer:

dimensions of the book are 2 in. by 24 in.    

Step-by-step explanation:

I assume the book is a rectangle

Let w = the width

     l = the length

A = lw = 48         P = 2w + 2l = 52

                                   w + l = 26

                                          l = 26 - w

w(26-w) =48

26w - [tex]w^{2}[/tex] = 48

[tex]w^{2} - 26 w + 48 = 0[/tex]

(w-2)(w -24) =  0

w = 2    or   w = 24

                           if w = 2, then l = 26 - 2 = 24

                           if w = 24, then l = 26 - 24 = 2

So, the dimensions of the book are 2 in. by 24 in.

Answer:

The answer is 9

Step-by-step explanation:

Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying

[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.

Step-by-step explanation:

(7 x 5) (9 x 3)

=(35) (27)

=35 x 27

=945

Answer:

If this is an expression, then 945

If these are invidual factors, then (35) (27)

Step-by-step explanation:

Situation one: Multiply the numbers. Paranthesis are not needed as multiplication is communitive, which leads me to believe they are factors written out in that form for some reason, cit. possibility two.
