4x+30=40

What you would do is subtract 30 from 30 and 40 which would give you 10 and then what you would do is divide the 10 by 4 to get 2.5.  Therefore X=2.5.  And to check your work you would plug in 2.5 in place of X and the answer to that equation should be 10.

Problems 1-8, name the sets of numbers to which each number belongs.
posledela

The name of the sets of the numbers to which each of the given number belongs is:

  1. 7 = Natural number. Integer. Rational number.
  2. √23 = Irrational number.
  3. л = Irrational number.
  4. O = Rational number. Integer.
  5. -0.5 = Rational number.
  6. -2.5 = Rational number.
  7. √0.09 = Rational number.
  8. -√0.9 = Irrational number.

<h3>What are sets of numbers?</h3>

These are the various types of number groups that exist for categorizing numbers.

Natural numbers are all positive numbers from 1 to infinity while integers are positive and negative whole numbers. A decimal cannot be an integer as a result.

Rational numbers are discrete which means that they are terminating and eventually stop going while irrational numbers will keep going to infinity and are therefore non-terminating.

ycow [4]
 <span>Because there are 20 coins plus four bars = 24 items to choose. You want to choose where to put the four bars, thus C(24,4). There are four bars, not five. Note that four bars divide the 20 coins into five sections. Five bars would divide it into six, but we only have five different kinds of coins to choose from.</span>
