A number consists of two digits whose sum is 12. If 16 is added to the number, then one of the digits is four times the value of

NeX [460]

Answer: The number is 12.

Step-by-step explanation:

Since we have given that

Sum of two digits = 12

Let the one's digit be 'x'

Let the ten's digit be '12-x'

So, Original number would be

$x+10(12-x)\\\\=x+120-10x\\\\=-9x+120$

If 16 is added to the number, then one of the digit is four times the value of the other.

According to question, we get that

$-9x+120+16\\\\=-9x+136$

so, the one's digit be 'x'.

Let the ten's digit be '4x'.

so, New number would be

$10x+4x=14x$

According to question, it becomes,

$14x=-9x+136\\\\14x+9x=136\\\\23x=136\\\\x=\dfrac{136}{23}=12$

So, the number would be

$-9x+120=-9\times 12+120=-108+120=12$

Hence, the number is 12.

Solnce55 [7]

Answer:

4/(√7 + √3)

Step-by-step explanation:

=> Multiply and divide by (√7-√3)

=> 4(√7 - √3)/((√7 + √3)(√7 - √3)

=> 4(√7 - √3)/((√7)² - (√3)²)

=> 4(√7 - √3)/((7) - (3))

=> 4(√7 - √3)/4

=> √7 - √3
