If 7 times a number is decreased by 33 the result is 15 less than 10 times number . find the number

 The number is 6.

Step-by-step explanation:

Let the number be x.

Given statement : "7 times a number is decreased by 33 the result is 15 less than 10 times number ."

i.e.

Add 15 on both sides and subtract 7x from both sides , we get

Divide both sides by 3 , we get

or

Hence, the number is 6.

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

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
