If 2/3=x/12 what is the value of x

4
8
18
24

Answer 1
Answer:

Hi!

(2)/(3)=(x)/(12)

(x)/(12)=(2)/(3)

(12x)/(12)=(2*12)/(3)

(12x)/(12)=x

(2*12)/(3)=8

Answer---->x=8

Explanation: First you had to switch sides to the problem. Then multiply by 12 from both sides. And simplify by 12x/12=8 or 2*12/3=8. And the answer should be x=8 is the right answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie
Answer 2

When you add the same number to both sides of an inequality , does the inequality remain true

Answers

Yes, The Reason Why, Is If You Add The Same To Both Sides, It Still Remains True. For Example:
10*5+2 < 10*6
But, If You Add 6 To Both Sides:
10*5+8< 10*6+6.
It Is The Same As
50+8<60+6.
In Conclusion, This Means That As Long As You Add The Same Number To Both Sides, Not Just One, But Both Sides, Your Inequality Will Always Stay The Same! (Unless You Change Something That You Aren't Supposed To Like Making Is (10+6)*5+2 < 6*10+6)
It would be the same, because the number is the same, so an example:
4*3 and 5*3, it would be 12 and 15, but if you add 5 to each side, then it would be, 4*3+5 and 5*3+5, then you would get 17 and 20. So to answer the question, yes the inequality would remain true because the number that you are adding to each side is the same. It is the same with dividing and multiplying and subtracting.

1. Since there is 2.54 to every inch, you would divide the meterstick of 100 centimeters back to inches.

100 / 2.54 = 39.37 rounded up.

2. 2 divided by 5 equals .40 of 100, so .40 of 35 would be 14. r = 14
So if you put it into the equation of A first

2/5 = 14/35 Which indeed is correct.

So the answer is A.

You survey your 22 classmates on there favorite color. There are 396 students at your school. How many students in the school do you predict would choose green as there favorite color

Answers

Answer:

The answer is 18 times the number given in the survey.

Step-by-step explanation:

The survey sample is an example of the 396 students. If there are 22 classmates in the survey, you need to turn 22 into 396 for it to work. 22 times 18 equals 396, therefore 18 times the number of green in the survey.

Solve the systems of equations 3x-4y=-2 and -x+8y=-23

Answers

We can use the subtraction method in order to solve for this system. First, line up the equations:

3x - 4y = -2
x + 8y = -23
_________
Our goal is to essentially get rid of one of the variables. We can do so by multiplying the first equation by 2:

6x - 8y = -4
x + 8y = -23
__________
7x = -27

x = -27/7

Input x into one of the equations to solve for y:
-27/7 + 8y = -23
-27 + 56y = -161
56y = -134
y = -134/56
y = -67/28

(-27/7, -67/28)
