Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5
2X + 50 = 5X - 10 subtract 2X from each side 50 = 3X - 10 add 10 to each side 60 = 3X divide each side by 3 20 = X check 2(20) + 50 = 5(20) - 10 40 + 50 = 100 - 10 90 = 90 checks
Divide the 20 over 50 by 10
3n+20=170 subtract 20 3n=150 divide by 3 n=50
To determine how many 50 cent pieces go into 10 dollars, you need to divide 10 by 0.50. This calculation shows that there are 20 fifty cent pieces in 10 dollars. This can also be expressed as 10 รท 0.50 = 20.
The value is 20. ((20/2) + 10) = 20 10 + 10 = 20

Well, isn't that just a happy little math problem! To find 50% of 20, you simply divide 20 by 2, which gives you 10. Then, you add that 10 back to the original 20, giving you a total of 30. So, 20 increased by 50% is 30.
2X + 50 = 5X - 10 subtract 2X from each side 50 = 3X - 10 add 10 to each side 60 = 3X divide each side by 3 20 = X check 2(20) + 50 = 5(20) - 10 40 + 50 = 100 - 10 90 = 90 checks
Divide the 20 over 50 by 10
I assume your 4 numbers are 5,10,15 and 20. If you add them and divide by the amount of numbers, you get 5+10+15+20, which is 50, divided by 4 which is 12.5
12.5 To find the average of a group of numbers, add all the numbers together and divide the sum by the number of numbers that were added together. Example: 5 + 10 + 15 + 20 = 50. Divide the sum (50) by 4 (you added four numbers together to get the sum): 50 divided by 4 = 12.5
round 52.75 to 50, for the tip : find 10% which is just divide by 10, so 10% is 5, then divide 5 by 2 to get 5%, which 2.5, add 5 and 2.5 together, that is llike adding 10 and 5% togetheer, gives you 7.5, then add 7.5 onto 50, so 57.50 alternatively, divide 50 by 15, add the answer to that onto 50
50
You can divide 100 by these numbers: 1, 2, 4, 5, 10, 20, 25, 50, 100.
Find 10% then times the 10% by 3 (to find 10% divide something by 10)
3n+20=170 subtract 20 3n=150 divide by 3 n=50
