Nghiep gave his mother half of his weekly earnings and then spent half of what was left on a new shirt. he then had $34. what were his weekly earnings (in dollars)?

Hence the weekly earnings of Nghiep= $136

Step-by-step explanation:

Let the weekly income of Nghiep be $ x.

As it is given that:

So now we will be left with= $(x/2).

   so the amount he spent on his shirt= $ (x/4)

Now he will be left with = $ (x/4).

Now it is given that the amount he had after spending on his shirt and giving to his mother= $ 34

i.e.

Hence, the weekly earnings of Nghiep= $136.

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

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
