Answer:

How does y vary with x?

This is called direct variation and to find proportionality, we use the formula y/x = K

Step-by-step explanation:

The first table's results would look like:

6:15

12:30

18:45

24:60

30:75

To do these, you divide the y values by the constant to receive x.

Add in the indicated base. 333 (sub)5 + 30 (sub)5
Vladimir [108]
In base 5 the place values (from right to left) are the ones place, the 5's place and the 25's place.  The highest digit you can write in any column is a 4.   

333 would be (3 x 25) + (3 x 5) + (3 x 1) which is 93 in base 10.
30 would be (3x5) + (0 x 1)  which is 15 in base 10.
The sum of 93 and 15 is 108 in base 10.
Now lets write that in base 5 -    We can have 4 25's so there will be a 4 in the 25's column.  Since 4 x 25 = 100 we still have to account for 8 to get to 108.
We can have 1 five  in the 5's columns since 1 x 5 is 5.  Now we have 3 left over which we can place in the one's column
Final answer 333₅ + 30₅ = 413₅
