y = 3 + 5 = 8

6x + 29 = 5
6x = 5 - 29 = -24
x = -24/6 = -4

What is the lengthof a hypotenuse of the right triangle ABC in the figure
Harrizon [31]
There is no figure. 
but you can use A^2 + B^2 = C^2
C is your hypotenuse. 
so if you have the other two lengths if you square them and add them you'll have C squared. So you'll have to find the square root of that number to actually find the length.

Trei copii au impreuna 45 de lei .
Ainat [17]

Answer:

Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.

Step-by-step explanation:

Lăsați suma primului copil să fie x.

Lăsați suma al doilea copil să fie y.

Lăsați suma al treilea copil să fie z.

Trei dintre ei au 45 de lei în total.

Aceasta înseamnă că:

x + y + z = 45 ________(1)

Al doilea are de două ori valoarea primului:

y = 2x

Al treilea are cu 15 lei mai mult decât al doilea:

z = 15 + y

=> z = 15 + 2x

Puneți valoarea y și z în (1):

x + 2x + 15 + 2x = 45

5x = 45 - 15 = 30

x = 30 / 5 = 6 lei

=> y = 2 * 6 = 12 lei

=> z = 15 + 12 = 27 lei

Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.

wolverine [178]
113  is one number. 131 is another
137, 173

I think that's all of them.

You can check if you google 'list of primes'.

Hold on  i'm not sure about 113 and 131 Is number 1 a prime number?  I dont think it is , So  that leaves us with  only 137 and 173.
