Un número desconocido es multiplicado por 11 y a este resultado se le resta 24. El resultado de esta operación es 86. Escribe en

kicyunya [14]

Answer: The number is 10.

Step-by-step explanation:

Let x be the required number.

Given: 11 is multiplied to the number then 24 is subtracted from that and the result is 86.

The mathematical statement for the given situation,

11x -24 = 86

To solve the equation, Add 24 on both sides , we get

11x - 24 +24 = 86+24

⇒ 11x = 110

Divide both sides by 11, we get

x = 10

hence, the number is 10.

What is the best estimate of the sum of the fraction? 31/4 +17/3 +8/18

Bogdan [553]

The best estimate of the sum of the expression given is $\rm 13 \dfrac {31}{26}$

What is a Fraction ?

A fraction is written as p/q , where q $\rm \ne$ 0

It is asked to determine the sum of the fraction

31/4 + 17/3 + 8/18

Taking the LCM of 4 , 3 , 18

LCM of 4 , 3 ,18 is 36

Therefore

$\rm \dfrac{ 31 *9 + 17 *12 + 8 *2}{36 }$

(279+204+16) /36

499 / 36

$\rm 13 \dfrac {31}{26}$

Therefore the best estimate of the sum of the expression given is $\rm 13 \dfrac {31}{26}$ .
