The sum of two consecutive natural numbers is 525. Find the numbers.

Luda [366]

Answer:

262 and 263 are consecutive natural numbers whose sum is 525.

Step-by-step explanation:

Natural number are a subset of real numbers consisting in positive integers (i.e. 1, 2, 3, 525) and two natural numbers are consecutive when distance between each other is equal to 1. ( $|x-y| = 1$ , $\forall\,x,y \in \mathbb{N}$ ) We can interpret the statement mathematically by means of the following expression:

$x + y = 525$

$x = n$

$y = n+1$

Where $x$ , $y$ , $n$ $\in \mathbb{N}$ .

This system is reduced to a single equation and solved afterwards:

$n +(n+1) = 525$

$2\cdot n + 1 = 525$

$2\cdot n = 524$

$n = 262$

Now we evaluate $x$ and $y$ to obtain the natural numbers:

$x = 262$

$y = 263$

262 and 263 are consecutive natural numbers whose sum is 525.

Solve (x + 6)/x - 4) = -16 0 (-12. 22) 0 1-4. 2) O {-4. 6)

Snowcat [4.5K]

Answer:

$3\frac{7}{17}$

Step-by-step explanation:

$\frac{(x + 6)}{(x - 4)} = - 16 \\ \\ x + 6 = - 16(x - 4) \\ x + 6 = - 16x + 64 \\ x + 16x = 64 - 6 \\ 17x = 58 \\ x = \frac{58}{17} \\ x = 3\frac{7}{17} \\$
