If Bill receives $12 for 3 days, then it can also be written as $4 for one day, if we divide by three. If we divide the $40 by the $4 Bill gets in one day, then we will get 10 days. Now for the next part, 3 weeks is 21 days. $4 x 21 days would be $84, which is not enough for the CD. Hope this answer helps! :)
Answer:
2 is the answer
Step-by-step2 explanation:
The way to do is is to write down expression, find factors of each polynomial and than cancel as many as possible. What remains is our simplified version of starting expression.
We start with this:
Now we factor every polynomial
now we can cancel fallowing factors:
5x-3, x-1 and x+5
after that we left with:
If the line is moving about 4 feet every 15 minutes, then a person will need about 3 hours to reach 50-foot line from the back to the front. It's because:
50 / 4 = 12,5 (that's how many quarters of an hour one needs to move 50 feet)
12,5 * 15 = 187,5 (that's how long it will take in minutes)
187,5 min = 3h 7min 30 sec
Approx. - 3h
