Please Help: Adelle solved the equation 4x/7-6= -20 as shown. Fill in the correct justification for each step. Will Mark Brainliest. Only answer if you are extremely 100%. Have to pass math. No Plagiarism Please.

Kindly check explanation

Step-by-step explanation:

Given the equation :

4x / 7 - 6 = - 20

4x / 7 = - 20 + 6 (move - 6 to the right hand side, the - sign attached to 6 changes to positive)

4x / 7 = - 14 ( - 20 + 6 = - 14)

4x = - 98 ( multiply both sides by 7 in other to isolate 4x)

x = - 24.5 (Divide both sides by 4, in other to isolate x and obtain it's value).

answer: i believe its b. if you sound out the sentences that sounds wrong.

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
