The sum of two numbers is -18. if the first number is 10, which equation represents this situation, and what is the second number?

a.
the equation that represents this situation is 10 − x = -18. the second number is 28.
b.
the equation that represents this situation is 10 + x = -18. the second number is -28.
c.
the equation that represents this situation is x − 10 = -18. the second number is -8.
d.
the equation that represents this situation is -10 + x = -18. the second number is -8.

The equation that represents this situation is 10 + x = -18. The second number is -28.

Step-by-step explanation:

The sum of two numbers is -18 and the first number is 10:

As an equation it would look like this:

10 + x = -18

To find the second number, we need to isolate it on one side of the equation, while keeping the expression true.

So first we subtract 10 from both sides:

10 -10 + x = -18 - 10

x = -28

Let's check!

10 + - 28 = -18

-18 = - 18

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
