A. 23 or -23
This is because how far x is away from 0 on a number line is it's absolute value which is represented by the bars.
b. 2.3
Same thing here. x is 2.3 because it's absolute value would have to be 2.3, which is what the answer says. (The negatives cancel each other out.)
c. 9
x is 9, so that 9+1 is 10, which is also ten in absolute value language here, and then that's the answer, too, so it all fits.
d. 3
Simplify the expression as k+4=7, and there ya go.

Which number line best shows how to solve −2 − (−10)? A number line from negative 10 to 10 is shown with numbers labeled at inte

Viktor [21]

Answer:

Ur answer is #1 = A number line from negative 10 to 10 is shown with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 2. Another arrow points from negative 2 to 8.

Step-by-step explanation:

The arrow from 0 to -2 represents the initial "-2" of the problem. <em>Adding </em>-10 would put an arrow of length 10 from that point to the left to -12. However, you are <em>subtracting </em>-10, so that arrow is reversed and goes from -2 to +8.
