Determine the distance between −18.26 and −2.45 on a number line.(1 point)
To determine the distance between -18.26 and -2.45 on a number line, we need to subtract the smaller number from the larger number.
|-18.26 - (-2.45)| = |-18.26 + 2.45| = |-15.81| = 15.81
Therefore, the distance between -18.26 and -2.45 is 15.81.
What is 17 4/9 + 5/9 − 8 − 10?(1 point)
To solve this expression, first combine the whole numbers:
17 + (-8) - 10 = 17 - 8 - 10 = 9 - 10 = -1
Next, add the fractions:
4/9 + 5/9 = 9/9 = 1
Finally, combine the whole number and the fraction:
-1 + 1 = 0
Therefore, the value of the expression 17 4/9 + 5/9 − 8 − 10 is 0.
