If your playing a game and get 15 coins 30 minutes. How many coins will you get in 1 hour and 40 minutes?
krok68 [10]

Answer:

You would get 50 coins in that time.

Step-by-step explanation:

To find this, we first need to find the unit rate. We can get that by dividing the amount of coins by the amount of time.

15 coins/ 30 mins = .5 coins per minute.

Now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.

.5 coins per min * 100 mins = 50 coins

Moses added two thirds of a number and one fifths of the same number to get a result of 39. What is the number?
Svetradugi [14.3K]

Answer:

45

Step-by-step explanation:

Let the number be X.

So 2/3 of a number would be (2/3)x and 1/5 of the same number would be (1/5)x.  Therefore, (2/3)x+(1/5)x=39.  Next, you combine like terms by converting the fractions: (10/15)x+(3/15)x=39.  Now, you add the fractions.  (13/15)x=39.  Lastly you divide both sides by 13/15 or multiply both sides by 15/13.  x=45.  That number would be 45.  

<u>If you would like to check</u>, you would do 2/3(45) or 90/3 which is 30 and do 1/5(45) or 45/5 which is 9.  30+9=39
