9x-22=23+4x Now you subtract 4x from both sides to get the variable on one side.. 5x-22=23 Now solve as you would solve a 2 step equation. 5x=45 Divide both sides by 5 to get the variable by itself. x=9

12 is 30% of ____ <br> (Please explain)
natka813 [3]

Answer:

40

Step-by-step explanation:

In word problems, the word "of" usually means multiply.  Thus, for example, 10% of $50 is $5.  This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply:    (1/10)(50) = 5

So, we often see equations like:

    R = (1/2)D        meaning R is 50% of D, or R is half of D

Let x = the number we want to find

This problem says:

 "12 is 30%       of    what number?"

  12 = (30/100) *        x

12 = (3/10)x

(10/3)12 = x             [multiply both sides by (10/3)]

    40 = x        

Checking (very important):      

 Is   12 = (3/10)(40)    ?

       12 = (3)(4)    ?

       12 = 12     ? yes

PLZ NO LINKS!!!!
Svetlanka [38]

The way the question is worded is a little confusing.

I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
