The number is 21.
21 ÷ 3 = 7
7 - 3 = 4
its easy just add them then multiply them then find the square root then add 5 million then divide!
Add all the numbers together and divide by the total number of the numbers. Example: average of 2 3 4 5 sum would b 14 and then divide by 4.
Add the numbers then divide the sum by the number of numbers you added e.g. average of 1,2,3,4 four numbers add em up 1+2+3+4 =10 divide the sum by the number of numbers 10/4 average of 1,2,3,4 is 2.5
12
-4 take the number 1-9 and add 4 and you've got the answer
Add them all together, then divide by the number of the amount of numbers. Say you wanted the mean of 2, 3, and 4. You would add 2, 3, and 4 then divide by 3, because there are 3 numbers.
add them all together then divide them by how many u added such as 1/3+2/3+3/3= 4/3 then divide 4/3 by three since u had three number which equal 1/4
4. Reverse the process to find the number: 7 is added to the product of 3 and a number to get 19. The last thing done is add 7; the reverse process of add is subtract, so subtract 7, leaving: The product of 3 and a number is 19 - 7 = 12. The reverse process to multiply (product) by 3 is divide, so divide by 3, leaving: a number is 12 ÷ 3 = 4
7
34?
the answer will always be 5

Divide 4 by 2, then multiply by 3 and then add 4

you add up all the grade totals and divide that number by the number of grades. A=4 B=3 C=2 D=1 F=0 For example if your child received 3 A's and 4 B's you will calculate it like this: 4+4+4+3+3+3+3= 24 then you divide 24 by 7(number of grades) the average is a 3.4 which is the grade point average. =)
add 3+3+3+3 divide it by 3 equals 4
