I'm not sure what this means, please help me I'll give you 10 points ;)

Answer 1

Answer:

So all the possible solutions are:

• $\bold{523,~400,~379~and,~378.6}$

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Add 78 to both sides:

• $78+78=$ Cancels Out

• $300+78=378$

So now we know the real answer, but it ask for all possible answers.

(Means anything larger than 300 when you plug it into x - 78 > 300.)

Numbers that are greater than 378:

  1.)  $377-78=299 > 300$  (False)

  2.)  $523-78=445>300$  (True)

  3.)  $0-78=-78>300$  (False)

  4.)  $-62-78=-140>300$  (False)

  5.)  $400-78=322>300$  (True)

  6.)  $379-78=301>300$  (True)

  7.)  $222-78=144>300$  (False)

  8.)  $378.6-78=300.6>300$ (True)
