Well, the chances are 3 to 1 in the first question, because there are three pencils and only one pen. In the second box it is a 50-50 chance that you will pick a crayon, because there are equal amounts of colored pencils and crayons in the second box. The numbers that I gave you aren't the fractions though. See if you can go from here.
3x + 5y = 10 Subtract 3x from both sides.
5y = -3x + 10 Divide both sides by 5.
y = -3/5x + 2
Answer:
answer for the question is 1.point R means that the unit rate is $14.00 per pound
It will take 2 hours for the ambulance to pass the police car.
Given that a police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour, and an ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour, to determine how long will it take for the ambulance to pass the police car, the following calculation must be performed:
- 72 x 0.25 = 18
- 81 - 72 = 9
- 18/9 = 2
- 72 x 0.25 + 72 x 2 = 162
- 81 x 2 = 162
Therefore, it will take 2 hours for the ambulance to pass the police car.
