Answer: C x=-4 and -10
Step-by-step explanation:
Answer:
A debt means subtracting from the original value so a debt of $300 can be expressed as -300.
$27
2.65 x 2 (since he has to go both to and from work each day) = $5.30
Add the daily cost of the water bottle (1.45) to make his total cost for one day, which is 6.75
Multiply this number by 4 (because he goes 4 days a week) to get $27 for one week.
B-8. This is because -4 to 0 is 4 and then 0-4 is 4. 4+4=8
