Using proportions, it is found that:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.
---------------------------
- Peter is walking at a rate of x km/h.
- MJ is biking 6 km/h faster than Peter, thus 6 + x km/h.
- Opposite directions, thus, their distance increases at a rate of (6 + 2x) km each hour, as
.
6 + 2x km each hour, 18 km after 1.5 hours, thus, the rule of three is:
1h - (6 + 2x) km
1.5h - 18 km
Applying cross multiplication:
Then:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.

So last week Paul worked 2.5x this week's hours, so he worked a total of 2.5x15= 37.5 hours last week.
So the book guy mark downed the price of the books by 46%, also known as 0.46. All decimals are less than 1. So then, what you do is you take b, which is the variable defining the price of the book, then you multiply it by 0.46. So the answer of b would be b x 0.46. For C, you must do 29 x 0.54, and that will give you the answer for C. Finally, in D, take the answer you got in C, and subtract that by 29. This will give you your answer.

Answer:
Yes
Step-by-step explanation:
Linear means a line, and x is not squared or anything in this equation. If you were to graph it, it would be a line.
