Answer:

Step-by-step explanation:

We are given that Twice the difference of a number and 2 is equal to three times the sum of the number and 4. And we have to tell the number.

Let the number be x

Its difference from 2 = x-2

Twice the difference =2(x-2)

Sum of number and 4 = x+4

Three times of the sum : 3(x+4)

Hence 2(x+2)=3(x+4)

2x+2×2=3x+3×4

2x+4=3x+12

Subtracting 12 and 2x from both sides.

4-12=3x-2x

-8=x

Hence the number is -8

(-3, 3)

Step-by-step explanation:

You need to find the median of the x value, and then the median of the y value, and that's your point. Good luck. I never liked graphing.

-4/9x=16/27 alguien que me ayude

Andre45 [30]

<h3>Answer</h3>

First multiply everything by 27

$- \frac{4}{9} x = \frac{16}{27} = \\ 27 \times ( - \frac{4 }{9}x) = 27 \times \frac{16}{27}$

Then approximate the terms with 27 if it's possible (27 and 9) (27 and 27)

$3 \times ( - \frac{4}{1} ) = 16$

So now multiply again

$3 \times ( - 4) = - 12$

And you have

$- 12x = 16$

$x = - \frac{16}{12} = - \frac{4}{3}$

You're welcome if it's right

At D.J.s Drink stand Erika ordered a cup of fruit punch made using 1/4 cup of lemonade 1/12 cup of cranberry juice. What fractio

Zepler [3.9K]

The fraction of the orange juice will be 2/3cup.

Why?

Since there is no additional information, let's assume that the fruit punch is made using just three juice fruits, lemonade juice, cranberry juice and the rest is orange juice.

We can calculate the fraction of the orange juice using the following information:

$FruitPunch=\frac{1}{4}Lemonade+\frac{1}{12}Cranberry+Orange\\\\1cup=\frac{1}{4}cup+\frac{1}{12}cup+Orange\\\\1cup-(\frac{1}{4}cup+\frac{1}{12}cup)=Orange\\\\1cup-(\frac{12+4}{4*12})=Orange\\\\Orange=1cup-\frac{16}{48}cup=1cup-\frac{1}{3}cup=\frac{3-1}{3}cup=\frac{2}{3}cup$

Hence, we have that the fraction of the orange juice will be 2/3cup.

Have a nice day!
