when 5 is subtracted from 3 times number the result greater than 6 .find the least whole number that satisfied the statement​
Alexandra [31]

Answer:

4

Step-by-step explanation:

Let x be a number.

The statement can be interpreted as:

  • 5 is subtracted <u>from</u> a number : x - 5
  • 3 times a number : 3x
  • A number is greater than 6 : x > 6
  • When 5 is subtracted <u>from</u> 3 times a number, the result is greater than 6 : 3x - 5 > 6

And then we simplify 3x - 5 > 6:

  • 3x - 5 > 6
  • 3x > 11
  • x > 11/3
  • x >  3.666...

To get the smallest whole number satisfying the inequality above, we can take the "ceiling" of 3.66 which is 4.

Note:

The ceiling of a number is the nearest integer (or in this case, nearest whole number) of a number. It can be denoted by ceil(x).

For example, the ceiling of 0.1 is 1. The ceiling of 5 is 5 since 5 itself is a integer.

Is this correct and if not how do I solve quickkkkkk!!!!!
noname [10]

Answer:

29 m

Step-by-step explanation:

The dashes mean that the lines are equal in length, so from this we can determine that the area marked 441 m² is a square.  

Area of a square = x², where x is the length of 1 side.  

Therefore, x = √441 = 21 m

Now we have a right-angled triangle with two legs of 20 m and 21 m.  We need to find the hypotenuse (labelled ?).  To do this, use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse.

Therefore,

    20² + 21² = c²

⇒ 400 + 441 = c²

⇒            841 = c²

⇒               c = √841

⇒               c = 29

So the side marked ? on the diagram is 29
