Which of the following is an expression for "doubling a number n and dividing by 3"

Answer:

x = 3

Step-by-step explanation:

cambia los signos : x - 2x-1=8-3x-3

like terms : -x-1=5-3x

variable: -x+3x=5+1 --> 2x=6

dividir: x=3

Answer:

DE=24

Step-by-step explanation:

We can see clearly that the two angles, angle A and angle F are congruent with one another, and since they are, we know the two triangles are shifted in a growth, not in an adjustment of angles. the hypotenuse doesnt matter, what does matter is the 5 and the 10, clearing showly the transition of Triangle ABC to Triangle DEF is times 2. Therefore, 12 times 2 is 24.

Answer:

Step-by-step explanation:

segment DE is what we want to find

notice that the two triangles are similar, similar here just means one is an exact copy of the other, except for scale.  One is an exact scale copy of the other.  sooooo  we can make some scaling of one side of one.. to the same side of the other.    here we want DE so .. see that BC is the same side on the other , smaller triangle?

now notice AB on the small triangle and FE on the bigger one... sooo just by observation we can see, that the bigger triangle is 2X bigger than the small one  ,  b/c  5 * 2 = 10  .  5 is the AB side of the smaller triangel and 10 is the same side but on the bigger triangle and 2 is our scaling factor.. got it?

So do the same on BC to find DE

12 * 2 = DE

24 = DE

see?  :)

Explanation:

The primes in this list are: {2,3,5}

The value 1 is not prime.

We have 3 primes out of 5 values total, so 3/5 = 0.6 = 60% of the list is prime. That makes 100% - 60% = 40% of values are not prime

This is the probability of getting a non-prime number.

Answer:

40%

Step-by-step explanation:

Prime numbers are whole numbers greater than 1 that only have 2 factors, for example, 2, 3, 5, 7, 11 are all prime numbers

In this data set 2, 3, and 5 are all prime numbers

3 out 5 numbers are prime

so the fraction is  [tex]\frac{3}{5}[/tex]

after you have found the fraction, you can divide it to find the percentage

In this case, when you divide the fraction you get 0.6

to make this a percentage you move the decimal place two spaces to the right. so 60%

60% are the values that are prime so you do this equation

100%-60%=40%

1779.84

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Mathematically, OPPOSITES are the same distance away from zero, but on opposite sides of zero on the number line. Use the drawing tools to plot a point at the opposite of each colored point. The absolute value of 0 is 0. Two numbers are opposites if they have the same absolute value but different signs. Opposites are the same distance from 0 on a number line, and they are on opposite sides of 0. The opposite of 0 is 0.

Answer:

239 cm(squared)

Step-by-step explanation:

NOTE: first calculate the square

9 x 15 = 135

then calculate triangle

subtract 22 from 9 to get 13

then subtract 15 and 7 to get 8

8 x 13 = 104

135 + 104 = 239 cm(squared)

Answer:

486

Step-by-step explanation:

1,985 + 12,000 + x = 14,471

x = 14471 - 12000 - 1985

x = 486

Answer:

486

Step-by-step explanation:

14471-12000-1985=486

Hope this helps :D

Answer:

8

Step-by-step explanation:  

x=average

(x+x+x+x)/4=average

to increase x by 2 you add 2

x+2=average

(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2

you'd have to increase the sum by 8 to make the numbers' averages' go up by 2

Answer:

  D.  h(x) = 5x² +12x +9

Step-by-step explanation:

The final constants are mostly different, so you can simplify your work by just figuring that one.

  h(x) = g(x) -f(x)

  h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D

__

If you want to figure the whole expression ...

  h(x) = g(x) -f(x)

  h(x) = 12x² +7x -7 -(7x² -5x -16)

  h(x) = 12x² +7x -7 -7x² +5x +16

  h(x) = (12 -7)x² +(7 +5)x +(-7 +16)

  h(x) = 5x² +12x +9 . . . . . matches choice D

Answer:

Step-by-step explanation:

this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?

maybe you can solve that?   I'll solve it below.. but.. if you can.. try it now, on your own

below is my answer... don't look until you have solved yours :P

80+70= 150kph

when will this have traveled 50Km?

you may be able to see that it will take 1/3 of an hour to travel 50 km

so 60 minutes times 1/3 = 20 minutes  :)

scale factor = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original, that is

scale factor = [tex]\frac{1.5}{6}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

4x-3y= 36-12=24 make me the brainlest

Answer:

Step-by-step explanation:

In order for us to be able to find our answer, we need to show our work.

-3(x-y=3) → -3x + 3y = -9

                 +2x - 3y = -1

____________________________

                  -1x = -10

                   -1      -1

We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.

x = 10

x - y = 3

10 - y = 3

-10       -10

_________________

-y = -7

-1     -1

We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.

y = 7

As a result, your answer will be B.

Answer: x=27

Step-by-step explanation: the perimeter is rim of the shape. Since you are already given the perimeter you would need to subtract all of the sides from that number. 93-18-18-15-15= 27 you will be left with the answer to the remaining side.
