The price p of a gallon of gas goes up to $0.05 cents on friday. on saturday the price goes down $0.03. write a expression with three terms to show the price of a gallon of gas on saturday.

The expression with three terms to show the price of a gallon of gas on Saturday is ⇒

Step-by-step explanation:

Given:

Price of a gallon of gas in dollars =

On Friday, the price goes up by = $0.05

On Saturday, the price goes down by = $0.03

To write an expression with three terms to show the price of a gallon of gas on Saturday.

Solution:

Initial price of a gallon given in dollars was =

On Friday the price increased by $0.05.

So, the price on Friday in dollars can be given as =

On Saturday, the price decreased by $0.03

So, the price on Saturday in dollars can be given as =

Thus, the expression with three terms to show the price of a gallon of gas on Saturday is ⇒

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
