Answer:
x + 52 + 78 = 180
Step-by-step explanation:
Hope it helps you in your learning process.
A die has six sides so you have a *blank*/6 chance of getting a certain number.
Since there are 3 even numbers on a die and 3 odd numbers. So the probability of rolling a even number would be:
3/6 or 1/2 or 50%
There is a one, one on a die so your chance of rolling a one the last time would be:
1/6 or about 16%
Hope this helps :) If you have any more questions just ask!

Step-by-step explanation:
---------------------------------------------------
Define x and y :
---------------------------------------------------
Let x the number of 2.5M downloads.
Let y the number of 4.6M downloads.
---------------------------------------------------
Construct Equations :
--------------------------------------------------
There was a total of 1230 downloads.
⇒ x + y = 1230
Total downloaded size was 4797M.
⇒2.5x + 4.6y = 4797
---------------------------------------------------
Find x and y :
---------------------------------------------------
x + y = 1230 -------------------- (1)
2.5x + 4.6y = 4797 ------------ (2)
---------------------------------------------------
From equation 1 :
---------------------------------------------------
x + y = 1230
x = 1230 - y // Take away y on both sides
---------------------------------------------------
Sub x = 1230 - y into equation 2 :
---------------------------------------------------
2.5 (1230 - y) + 4.6y = 4797 // Sub x = 1230
3075 - 2.5y + 4.6y = 4797 // Apply distributive property
3075 + 2.1y = 4797 // Combine like terms
2.1y = 1722 // Take away 3075 from both sides
y = 820 // Divide by 2.1 on both sides
---------------------------------------------------
Sub y = 820 into equation 1 to find x :
---------------------------------------------------
x + y = 1230
x + 820 = 1230 // Sub y = 820
x = 410 // Take away 820 from both sides
---------------------------------------------------
Find the number of each type of downloads :
---------------------------------------------------
Number of 2.5M downloads = x = 410
Number of 4.6M downloads = y = 820
-------------------------------------------------------------------------------------
Answer: There were 410 downloads for the standard version.

<span>There are 16oz in a pound, so in two pounds there are 32oz. This makes 32oz per week. To find out how many oz per day, you must divide the oz per week by the number of days in a week. 32/7 = 4.57142857143. 2lb/wk = 4.6oz/day to one decimal place.</span>
