Use the following number line to determine if expressions are true or false

false

true

false

Step-by-step explanation:

if that would mean that "a" is on the left of 0 so the first one is false

every whole value is greater that 0, (except for 0) so the second one is true

if that would mean that "a" is 0 but by the line we see is false

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
