Use the picture below to find the distance between the point below sea level (-155) to the point above sea level (1025).
*
1 point
1180
870
The distance between the point below sea level (-155) to the point above sea level (1025) is given by the absolute difference of the two values:
|(-155) - 1025| = |-1180| = 1180
So, the correct answer is 1180.
9. Leah borrowed $20 from her brother. Which integer best represents how much money Leah owes?
*
1 point
20
-20
Since Leah borrowed $20 from her brother, the integer that best represents how much money Leah owes is -20.
10. Compare the numbers 10 and -2.
*
1 point
10 = -2
10 ≠ -2
10 < -2
10 > -2
10 > -2
11. Put the temperatures in order from greatest to least.
-11, 12, 0, 3, -5, 10
*
1 point
-11, 12, 0, 3, -5, 10
-11, -5, 0, 3, 10, 12
-5, -11, 0, 3, 10, 12
12, 10, 3, 0, -5, -11
12, 10, 3, 0, -5, -11
Write an inequality to show the relationship between the largest and the smallest temperature.
*
1 point
10 > -11
10 < -11
-11 < 10
13. How far away from each other would 10 and -11 be on the thermometer (number line)?
*
1 point
1 space
21 spaces
On the number line, the distance between 10 and -11 would be 21 spaces.
