I think of number I add 14 to the number and multiply the result by 3 if my final answer is 51 what number did I think of

erma4kov [3.2K]

Answer:

-1

Explanation:

Let the number be x.

Then the equation will be:

3(x+18) = 51

=> 3x + 54 = 51

=> 3x = 51 - 54

=> 3x = -3

=> x = -3/3

=> x = -1

So, the number you thought of is -1.

prisoha [69]

Answer: Greater than 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

$\Rightarrow F>10\ N$

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement
