I am a number less than 100. I am a product of two prime numbers. If you reversemy digits, I am a prime. The sum of my digits is
almond37 [142]

Answer:

You are number 34

Step-by-step explanation:

* Lets explain how to solve the problem

- The number is less than 100

∴ The number is 2-digit  number

- The number is the product of 2 prime numbers

∴ The two prime numbers could be two of these numbers:

   2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , 31 , 37 , 41 , 43

∵ The number is less than 100

∴ The two prime numbers are 1-digit numbers OR one of them

   is 1-digit and the other is 2-digit

- The sum of its digits is a 1-digit

∴ The sum of its digits is less than 10

- One of its digit is a square number

∴ One of its digit is 1 or 4 or 9 because they are square numbers

* Look to the prime number above the number and chose two of

  them try to find the answer

- Start with the product of 1-digit prime numbers

∵ 2 and 7 are prime numbers

∵ 2 × 7 = 14 and the sum of its digits is less than 10 (1 + 4 = 5)

∵ 14 < 100

∵ The reversed of its digits obtained 41 which is a prime number

∵ 4  and 1 are a square number (1² = 1 or 2² = 4)

∴ The number is not 14

- Chose one of them 1-digit and the other 2-digit

∵ 2 and 17 are prime numbers

∵ 2 × 17 = 34 and the sum of its digits is less than 10 (3 + 4 = 7)

∵ 34 < 100

∵ The reversed of its digits obtained 43 which is a prime number

∵ 4 is a square number (2² = 4)

∴ The number is 34

* You are number 34

Anybody know the answer to this
Phoenix [80]

Answer:

x = 2

Step-by-step explanation:

The blue line represent the full line length.

We can add the parted black segments together and set it equal to the line.

11 + 6x - 2 = 6x + 9

10x + 1 = 6x + 9

10x = 6x + 8

4x = 8

x = 2

Q is the midpoint of line segment PR. PR=9x-31 and QR=43 ; find x
bulgar [2K]

notice that, if Q is the midpoint of PR, that simply means that PQ = QR = 43.


\bf \boxed{P}\underset{\leftarrow 9x-31 \to }{\stackrel{\stackrel{\downarrow }{43}}{\rule[0.35em]{10em}{0.25pt}}Q\stackrel{43}{\rule[0.35em]{10em}{0.25pt}}}\boxed{R}&#10;\\\\\\&#10;9x-31=43+43\implies 9x-31=86\implies 9x=117&#10;\\\\\\&#10;x=\cfrac{117}{9}\implies x=13
