3/2x-5=7<br><br> Yo can someone explain this?
Contact [7]

Answer:

x = 8

Step-by-step explanation:

  1. Write it out: \frac{3}{2}x - 5 = 7  
  2. Add 5 to each side, so it now looks like this: 3/2x = 12
  3. Divide each side by 3/2 to cancel out the 3/2 next to x. It should now look like this: x = 8

I hope this helps!

Marta is making two different charms for necklace one charm has a 1 cm diameter and a 3.14 cm circumference of a similar charm h
EastWind [94]
From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference."  Please, would you use proper punctuation in your writing, for greater clarity:

"A</span><span> similar charm has a diameter of 4 cm.  What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is 

C=</span>\pid               or  C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.

mezya [45]
3 pen + 2 pencil = .47
2 pen + 3 pencil = .38

 2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)

 6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
            - 5 pencil = -.2
                 pencil = .04

3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13

Pen = 13 cents and pencil = 4 cents
