How can the equation x + 2 = 5 be solved using algebra tiles? A. add two 1-tiles to each side B. remove two 1-tiles from the left side C. remove two 1-tiles from each side D. remove five 1-tiles from each side

C

Step-by-step explanation:

X + 2 = 5

If we try to add 2 on each side, we get X + 2 + 2 = 5 + 2 which comes out as X + 4 = 7.

If we remove 2 from the left side, we get X + 2 -2 = 5 and we'd get X = 5, but if we cannot remove on one side without removing from the other.

If we remove 5 from both sides: X + 2 - 5 = 5 - 5, which is X + (-3) = 0 And we would need another step to determine X

So removing 2 from both sides gives us X + 2 -2 = 5 - 2 which is X = 3, which is a good result.

As a result, the correct answer is C.

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
