Which number line represents the solution to the inequality x - 3 > 2
Ivahew [28]

Answer: x > 5

Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.

Since 3 is being subtracted from x, we add 3 to

both sides of the inequality to get x > 5.

When graphing x > 5, we have an open circle on 5 and the

open circle tells us that 5 is not part of our answer.

Then we draw an arrow going to the right to represent

all possible solutions to this inequality, any number greater than 5.

Which of the following expressions is correct?
masya89 [10]

Answer:

The correct answer is: [A]: " -(-21)  =  21 " .

________________________________

Step-by-step explanation:

________________________________

Let us examine the answer choices given.

________________________________

Choice:  [A]:  " -(-21) = 21 .  This is correct;  

     → since a "negative value of negative value" is a "positive value" ; as shown in this case.  The equal sign holds true, since the

"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."

________________________________

Choice: [B]:  " -(-21) = -21 .  This is incorrect.  As explained above:

    → a "negative of negative" is a "positive value"  .

This answer choice shows that a "negative of negative"; is a "negative" :

                                                      → which is:  INCORRECT.

    → Rule out:  "Choice:  [B]."

________________________________

Choice: [C]:  " -(21) = 21 .  This is incorrect.  The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.

   → Rule out:  "Choice:  [C]."

________________________________

Choice: [D]:  " (-21) = 21 ";  This is incorrect.  In a conceptually similar way as explained above—(for  "Answer Choice:  [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].

  → Rule out:   "Choice:  [D]."

________________________________

The correct answer is:  [A]:  " -(-21) = 21 " .

________________________________

Hope this is helpful to you!

   Best wishes!

OverLord2011 [107]
If we add $0.14 until we get $21.64, we would add it 154.572 times. To check this answer and make sure I’m right, do this equation: 0.14 x 154.572, then you would get 21.64.

The correct answer is 154.572 minutes.
