Do the ratios 8:10 and 5:4 form a proportion?
sukhopar [10]

Elena-2011 [213]

Answer:

You would have 4 red marbles and 8 blue marbles since you didn't return the ones you took out to the bag.

Step-by-step explanation:

6 - 2 = 4

The 8 would stay the same

If 12 is replaced with 3 in the following set, what will happen to the value of the range? 28, 45, 12, 34, 36, 45, 19, 20
anzhelika [568]
The range is the number of units between the smallest and largest number. organising your numbers from smallest to largest:

12, 19, 20, 28, 34, 36, 45, 45

in your case 12 is the smallest number of your set. lowering it to 3 would increase the distance between the two numbers, therefore increasing the range

hope that helps :)
