Step-by-step explanation:

three and two fifths = 3 2/5

+

three and four sixths. = 3 4/6

--------------------------------------------------

 3 2/5   ---->   3  12/30

+ 3 4/6 ---->   + 3 20/30

---------------    -----------------

?????????          6 32/30 or 7 2/30

The LCM would be 30.

2/5 = 12/30

4/6 = 20/30

Answer:

7 1/15

Step-by-step explanation:

Rewriting our equation with parts separated

=3+2/5+3+4/6

Solving the whole number parts

3+3=6

Solving the fraction parts

2/5+4/6=?

Find the LCD of 2/5 and 4/6 and rewrite to solve with the equivalent fractions.

LCD = 30

12/30+20/30=32/30

Reducing the fraction part, 32/30,

32/30=16/15

Simplifying the fraction part, 16/15,

16/15=1 1/15

Combining the whole and fraction parts

6+1+1/15=7 1/15

Who got the answer to this ? <br> (4x^2+6+7)-(-8x^2-2x+6)
Andru [333]

Answer:

12x^2+2x+7

Step-by-step explanation:

Distribute the Negative Sign:

=4x^2+6+7+−1(−8x^2−2x+6)

=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)

=4x^2+6+7+8x^2+2x+−6

Combine Like Terms:

=4x^2+6+7+8x^2+2x+−6

=(4x^2+8x^2)+(2x)+(6+7+−6)

=12x^2+2x+7

I have no clue how to do any of these problems so if anyone knows any an explanation would be nice.

#1).  The length of the whole circumference is (π · D) = 12π .

         120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.

#2).  60° is 1/6 of 360°.
         So arc-CD is 1/6 of the whole circumference (which is given).

#3).  The circumference of the circle is (π·D) = 20π .

         70° is (70°/360°) of the whole circle, so arc-XY
         is  (70/360) of the whole circumference.

#4).  Sorry, I don't remember anything right now about
         angles between chords. 
         I hope what I've given you so far is worth 5 points.
