Twice a number decreased by 9 is greater than 11 what is the number?
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!
What does the math term greater than mean?
"Greater than" is the same as "Bigger than". In math, it really refers to where a number is located on the Number Line. If you have two numbers that are NOT equal and you see where they are on the number line, then the BIGGER of the two numbers, the one to the RIGHT, is greater than the other. 10 is greater than 2, for example. 10 is greater than 0, and 10 is also greater than -114.
What does more than mean in a math problem?
"more than" means "greater than". 100 is greater than 1 because it's a bigger number. 0 is greater than -3 because 0 is a greater number.
How can you tell whether the percent of a number will be greater than less than or equal to the number?
100% equals the number. Less than 100% is less than the number. Greater than 100% is greater than the number.
