Can every even number be written as a sum of two primes?
astraxan [27]
The Goldbach Conjecture is a yet unproven conjecture stating that every even integer greater than two is thesum of two prime numbers. The conjecture has been tested up to 400,000,000,000,000. Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics.

Solve for x: three fourths times x plus five fourths equals four times x
Nostrana [21]

Answer:

x equals  five thirteenths

Step-by-step explanation:

To solve this, we will follow the steps below;

\frac{3}{4} ×  x  + \frac{5}{4}  =  4 × x

\frac{3x}{4} + \frac{5}{4}   = 4x

\frac{3x + 5}{4} =  4x

Multiply both-side of the equation by 4

\frac{3x + 5}{4} × 4=  4x × 4

On the left-hand side of the equation 4 will cancel-out 4, thus the equation becomes;

3x + 5 = 16x

subtract 3x from both-side of the equation

16x - 3x = 5

13x = 5

Divide both-side of the equation by 13

\frac{13x}{13} = \frac{5}{13}

(On the left-hand side of the equation 13 at the numerator will cancel-out 13 at the denominator while on the right-hand side of the equation 5 will be divided by 13)

x = \frac{5}{13}

x equals  five thirteenths
