The strategy that can help a reader find the central ideas of a text is "looking for supporting details and repetition of key words in the text." By examining the supporting details provided in the text and identifying any repetition of key words or phrases, a reader can piece together the main points or central ideas that the author is conveying. These repetition and supporting details often serve as clues to the main focus or argument of the text.
Use the additive inverse to find 8.76 − 26.54.(1 point)
To find the additive inverse, you simply change the sign of the number. The additive inverse of 8.76 is -8.76, and the additive inverse of 26.54 is -26.54.
So, to find 8.76 − 26.54, you can rewrite it as 8.76 + (-26.54).
Calculating the sum, 8.76 + (-26.54) gives you -17.78.
Therefore, 8.76 − 26.54 is equal to -17.78.
Use the additive inverse to find −12 2/3−(−8 5/6). Write the answer as a mixed number.
(1 point)
To find the additive inverse, you change the sign of the number.
So, the additive inverse of -12 2/3 is 12 2/3, and the additive inverse of -8 5/6 is 8 5/6.
Now, rewrite the expression -12 2/3 - (-8 5/6) as -12 2/3 + 8 5/6.
Next, find a common denominator for the fractions, which is 6.
Converting the mixed numbers to improper fractions, you will have -38/3 + 53/6.
To add these fractions, you need to find a common denominator, which is 6.
Now, the expression can be rewritten as -38/3 + 53/6.
To add these fractions, you need a common denominator. Multiplying the denominators (3 * 6 = 18), you get:
(-38/3 * 6/6) + (53/6) = -228/18 + 53/6.
Now, the denominators are the same, so you can add the numerators:
-228/18 + 53/6 = (-228 + 159)/18 = -69/18.
Simplifying the fraction, you get -23/6.
Now, convert the improper fraction back to a mixed number.
Divide 23 by 6:
23 ÷ 6 = 3 with a remainder of 5.
Therefore, the answer is -3 5/6.
What is the distance between −8 and 16 on a number line? (1 point)
To find the distance between two numbers on a number line, you subtract the smaller number from the larger number and take the absolute value of the result.
In this case, the smaller number is -8 and the larger number is 16.
The distance between -8 and 16 is |16 - (-8)|.
Simplifying the expression, you have |16 + 8|.
Adding 16 and 8 gives you 24.
Therefore, the distance between -8 and 16 on a number line is 24.
What is the distance between 18.25 and −7.4 on the number line? (1 point)
To find the distance between two numbers on a number line, you subtract the smaller number from the larger number and take the absolute value of the result.
In this case, the smaller number is -7.4 and the larger number is 18.25.
The distance between 18.25 and -7.4 is |18.25 - (-7.4)|.
Simplifying the expression, you have |18.25 + 7.4|.
Adding 18.25 and 7.4 gives you 25.65.
Therefore, the distance between 18.25 and -7.4 on the number line is 25.65.
Subtract 12 − (−8).(1 point)
$$
To subtract 12 - (-8), you can rewrite it as 12 + 8, because subtracting a negative is the same as adding a positive.
Calculating the sum, 12 + 8 gives you 20.
Therefore, 12 - (-8) is equal to 20.

To find the additive inverse, you change the sign of the number.
So, the additive inverse of -123.45 is 123.45, and the additive inverse of -234.76 is 234.76.
Now, rewrite the expression -123.45 - (-234.76) as -123.45 + 234.76.
Calculating the sum, -123.45 + 234.76 gives you 111.31.
Therefore, -123.45 - (-234.76) is equal to 111.31.

To find the additive inverse, you change the sign of the number.
So, the additive inverse of -24 4/5 is 24 4/5, and the additive inverse of -(-6 7/10) is 6 7/10.
Now, rewrite the expression -24 4/5 - -6 7/10 as -24 4/5 + 6 7/10.
Next, find a common denominator for the fractions, which is 10.
Converting the mixed numbers to improper fractions, you will have -124/5 + 67/10.
To add these fractions, you need to find a common denominator, which is 10.
Now, the expression can be rewritten as -124/5 + 67/10.
To add these fractions, you need a common denominator. Multiplying the denominators (5 * 2 = 10), you get:
(-124/5 * 2/2) + (67/10) = -248/10 + 67/10.
Now, the denominators are the same, so you can add the numerators:
-248/10 + 67/10 = (-248 + 67)/10 = -181/10.
Now, simplify the fraction:
-181/10 can be written as -18 1/10.
Therefore, -24 4/5 - -6 7/10 is equal to -18 1/10.

To find the distance between two points on a number line, you subtract the smaller number from the larger number and then take the absolute value of the result.
In this case, the smaller number is -7.2 and the larger number is 6.5.
The distance between 6.5 and -7.2 is |6.5 - (-7.2)|.
Simplifying the expression, you have |6.5 + 7.2|.
Adding 6.5 and 7.2 gives you 13.7.
Therefore, the distance between 6.5 and -7.2 on a number line is 13.7.
