Which of the following is an equivalent form of the compound inequality −22 > −5x − 7 ≥ −3?
ioda
The answer is: [A]: " <span>−5x − 7 < −22 and −5x − 7 ≥ −3 "
______________________________________________
Explanation:
___________________________
We are the given the following compound inequality:
__________________
" </span><span>−22 > −5x − 7 ≥ −3 "
__________________________
Consider Answer choice: [A]: </span><span>−5x − 7 < −22 and −5x − 7 ≥ −3
</span><span>____________________________________________
Do both of these given in "Answer choice [A]" hold true?
______________________________________
  First, does: </span>−5x − 7 < −22 hold true?  
___________________________________
<span>Yes, because, in the compound inequality given:
___________________________________
</span><span>−22 > −5x − 7 ; which is another way of saying that:
</span><span> __________________
 </span>−5x − 7 < −22 .
<span>____________________
Second does: </span><span> "−5x − 7 ≥ −3 " , hold true?
</span>_____________________________
Yes, because, in the compound equality given, 
________________
<span>−5x − 7 ≥ −3 ; which explicitly tells us that it holds true.
</span>_________________
Thus, "Answer choice: [A]: <span>−5x − 7 < −22 and −5x − 7 ≥ −3 " is a correct answer.
___________________
There could be other correct answers, so let us examine the other answer choices:
____________________
Consider "Answer choice: [B]: </span><span>−5x − 7 > −22 and −5x − 7 ≥ −3 ;
</span>__________________________
Do EACH of these hold true in "Answer choice "B"?
_______________
First let's examine:
_________________
 −5x − 7 > −22 ; Does this hold true?
_____________________
No! Because in the compound inequality given,
−5x − 7 < −22 ; so we already know that "Answer choice: [B]" is incorrect; and thus, it makes no difference whether the other part of "answer choice [B]" is correct or incorrect.
_______________________
Let us consider: "Answer choice: [C]: <span>5x > −22 and −7 ≥ −3" .
 Do these hold true with respect to our given compound inequality?
____________________________________________________
No; since NEITHER one of of this 2 (two) components given are are part of our compound inequality given.
__________________________________________________
Furthermore, the particular component given: " </span>−7 ≥ −3" does not make sense. "Negative 7" is not 'greater than or equal to' "Negative 3".   -7 <span>≠ -3 . Additionally, "-7" is LESS THAN—not GREATER THAN—"-3". 
</span>_________________________________________________
Also, "−5x > −22" is NOT part of the compound inequality given. So, "Answer Choice: [C]:  <span>−5x > −22 and −7 ≥ −3" ; is INCORRECT.
___________________________________________________
Additional note: "</span> −5x < −22" is NOT part of the compound inequality given, either.
____________________
The [incorrect] "Answer Choice: [C]:  "<span>−5x > −22 and −7 ≥ −3" ; can be somewhat deceptive.

The compound inequality given:
___________________________
</span>" −22 > −5x − 7 ≥ −3 "  ;   should be viewed as:
_______________________________________
" −22 > (−5x − 7) ≥ −3 " ;
_____________________________________
and the term, "(−5x − 7)" should be treated as one separate term—just like the terms: "(-22)", and "(-3)".
_______________________________________________
Let us consider "Answer choice: [D]: <span>−5x − 7 < −22 and −5x − 7 ≤ −3 " .
_______________________________________________
Start with: </span>−5x − 7 < −22 .  Does this hold true for our original compound inequality? 
________________
Yes!  (Since in our original compound inequality; "<span>−22 > −5x − 7" ;
</span> and this component of 'Answer choice: [D]' — "−5x − 7 < −22 "— is another way of saying that: "−22 > −5x − 7" (as denoted in our original compound inequality).
___________________
Now, we shall examine the second component of
'Answer choice: [D]' — "<span>−5x − 7 ≤ −3 ".
_____________________
D</span>oes this hold true for our original compound inequality? 
_______________________
No!  This second component given in our 'Answer choice'—is:
<span> "-5x − 7 ≤ −3" ; and in our original compound inequality: 
_______________
"</span><span>−5x − 7 ≥ −3 " ! 
</span>________________________
As such, since one of the compounds in 'Answer choice: [D]' is incorrect; 
 _______________________________________________
Answer choice: [D]: "<span>−5x − 7 < −22 and −5x − 7 ≤ −3" ;  is incorrect.
______________________________________________________</span>

8. Reasoning Matt's family is thinking
Korvikt [17]

Answer:

They would be able to save 20$

Step-by-step explanation:

To find how much 4 individual passes are, you do 25 times 4. 25 times 4 equals 100. So, you would have to pay 100$. So, the family pass is a better deal. They can save 25$.
