Three Working backwards from 11 then add 4 to make 15 then dividing 15 by 5 makes 3
11-9=v
Yes, the number 143 can be divided by several numbers. When dividing 143 by 1, the result is 143. When dividing by 11, the result is 13. When dividing by 13, the result is 11. So, 143 can be divided by 1, 11, 13, and itself.
11
11 is a prime number because the factors of 11 are only 1 and itself.
"Decreased by" just means "minus," so that's C-11.
The expression for eleven decreased by a number can be written as 11 - x, where x represents the unknown number being subtracted from eleven. This expression represents the operation of subtraction, where the value of x will determine the final result after subtracting from eleven.

1/3x - 11 = 38 Therefore, 1/3x = 49 Therefore, x = 49 x 3 = 147
11-9=v
Its 11
Yes, the number 143 can be divided by several numbers. When dividing 143 by 1, the result is 143. When dividing by 11, the result is 13. When dividing by 13, the result is 11. So, 143 can be divided by 1, 11, 13, and itself.
11 is a prime number because it has only two factors which are itself and one
IF the question means: What number, multiplied by 2, and reducing the answer by 9, gives a result that is greater than 11?ANSWER: Any number greater than 10.Let's try 11.2 x 11 = 22.22 - 9 = 13, which is greater than 11.But if we try 10 ...2 x 10 = 20.20 - 9 = 11, but 11 is not greater than 11! So we need a higher number than 10.Try it for yourself with ANY number greater than 10!-----------------------------------------------------------------------------------------Alternative answer.If the question means "What number decreased by 9, and then doubled, produces a number greater than 11?"...... then work it out this way, working backwards:What number is greater than 11?We could say '12' is greater than 11.Half of 12 is 6. Add 9 to 6 = 15.So, now, let's try 15.15 decreased by 9 is 6.Twice that number is .... 12 (2 x 6), which is greater than 11!But this would work for ANY number from 15 upwards!

It is: 11*11 = 121
