The difference of three times a number and five is four. find the number

The difference of three times a number and five is four. Then the number is 3

Solution:

Given that,

Difference of three times a number and five is four

We have to find the number

Let us frame a equation using the given information and solve the sum

Let the number be "n"

Difference of three times a number and five = 4

Three times n - 5 = 4

3n - 5 = 4

3n = 9

On dividing 9 by 3 we get 3

n = 3

Thus the required number is 3

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
