plz help!! math isn’t my thing!! i’ll give brainliest!!

18! is common to each term in the sum:

18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400

The largest prime factor of 18! is of course 17.

Meanwhile,

400 = 16×25 = 2⁴×5²

so the largest prime factor of 18! + 19! + 20! is 17.

Answer:

2x

Step-by-step explanation:

I'm going to guess that the diagram means that you have 4*(+x) and you subtract 2(x) leaving you with 2x

The ones are a bit harder

(6*1) + (6*-1) = 0

Answer:

[tex]ax - y + z = b \\ ax = b + y - z \\ \\ x = \frac{ b + y - z }{a} [/tex]

I hope I helped you^_^

Answer:

x < 0 : 1/2 < 1 ÷ 1/2 ↔ 1/2 < 2 (đúng)

x > 0: 2 < 1/2 (sai)

Answer:

3/14

Step-by-step explanation:

5/7 = 10/14

1 - 10/14 - 1/14 = 1 - 11/14 = 3/14

Answer:

73

Step-by-step explanation:

Angle JID is supplementary to Angle JIH so:

180- Angle JIH= Angle JID

180-107=73

Angle JID is opposite to Angle AJF(angle x)

Opposite angles are always equal

Angle JID=Angle AJF(x)

73=Angle AJF(x)

Answer:

Angle x = 76⁰

Hey there! I'm happy to help!

A translation is just when they are staying the same. You just move the figure along but it doesn't switch the way it is facing.

A reflection is when it is like going over a mirror. It's kind of like it rolls over. So if you are facing left on the ground and you roll over then you are facing the right. That's basically what a reflection is.

A rotation is pretty self explanatory, it's when you twist it sideways, upside down, etc. A rotation can also end up in the same position as a reflection. For example if you diagonally reflect something it is the same as a 180 degree rotation, and that might be what is stressing you out.

With your answers, I'm assuming each number has all three possible answers, so if one seems to have both, just see which answer you haven't used yet.

1) Rotation, Translation Reflection

2) Rotation, Reflection, Translation

3) Translation, Rotation, Reflection

4) Rotation, Reflection, Translation

5) Reflection, Rotation, Translation

6) Reflection, Rotation, Translation

Have a wonderful day and keep on learning! :D

Answer:

honestly, the graph look totally fine...

If one ere pressed to find something to complain about it, one could suggest that  you do not know if this was the starting price of the stock or the ending price of the stock each day?... One could also argue that to be a bit more meaningful you might want to know the range of prices during each day...

look up what is called a candle stick graph.. each day looks like a candlestick... the top is the highest value each the bottom the lowest, and there is a line in the candle that  shows the closing price

Answer: -13/3

Step-by-step explanation: -1  5/8  -> -13/8        2  2/3->  8/3

-13/8 x 8/3 = -104/24

                  = -13/3  OR  -4   1/3      

Answer:

(1,4)

Step-by-step explanation:

To find the x coordinate of the midpoint, average the x coordinates of the endpoints

(5+-3)/2 = 2/2 =1

To find the y coordinate of the midpoint, average the y coordinates of the endpoints

(7+1)/2 = 8/2 =4

Answer:

The answer is [tex]\frac{7\pi }{12}^{c}=105^{0}[/tex]

Step-by-step explanation:

The expression is

[tex]\frac{7\pi }{12}^{c}\\= \frac{7\pi }{12}*\frac{180}{\pi }^{0} \,;[1^{c}=\frac{180}{\pi}^{0}]\\=7*15\\=105^{0}[/tex]

Answer:

PERIMETER=Y+2Y+11+-3Y-9+Y^2+5Y-1+6Y^2

=7Y^2+4Y+1

Answer:

(-6,1)

Step-by-step explanation:

-x + y = 7 [Equation (1)]

2x + 5y = -7 [Equation (2)]

Multiplying equation (1) by 5, to make the coefficients of y equal in both equations.

5(-x + y) = 5(7)

=> -5x + 5y = 35 [Equation (3)]

Subtracting equation (3) from equation (2).

(2x + 5y) - (-5x + 5y) = -7 - 35

=> 2x + 5y + 5x - 5y = -7 - 35

=> 7x = -42

=> x = -42/7

=> x = -6

Putting the value of x in equation (1).

-(-6) + y = 7

=> 6 + y = 7

=> y = 7 - 6

=> y = 1

So, x = -6 and y = 1.

Answer:

loss = 24, loss % = 10

Step-by-step explanation:

amount he spent = 12*20 = 240

amount he earnt = 12*18 =216

loss = 240-216 = 24

loss % = 24/240 x 100% = 10%

Answer:

40545.50 mill

Step-by-step explanation:

so the average rate from 2010 to 2014 is a change of 4 years with a  increase of 2719.25 milllion per year so if that rate started at the 2010 value (35107 million) then if you add the average rate twice you get how much they would of made in 2012 so 35107 plus 2719.25 plus 2719.25 you get 40545.50 million  so that the answer oh yea and its like a 5 million pattern over 2 years that why average rate is 2.5ish

Answer:

Let x = # of ounces in a bag

x ≥ 23.75 and x ≤ 24.25

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

By the Vertical Angles Theorem that states the vertical angles are congruent.

4x+8 = 2x + 28

    -8           -8

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

4x = 2x + 20

-2x    -2x

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

2x = 20

/2      /2

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

x = 10

Answer:

[tex](4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10[/tex]

Vertical angel are always Equal ( = )
