2n = 24 n = 12
The equasion would be 10x 1/j = 5x1/9 (if j equals some number) so the answer would be j=18.
That's not even a question. It's only a statement that says that some number is equal to itself.
5*(3+x)=15+5x Fifteen plus five times that number
Well, well, well, aren't you a tricky one. The answer to your little riddle is -3 times -10, which equals 30, and also equals -11 when you add them together. Math can be fun when you throw in some negatives, huh?
515
7 times some other unknown number then add 8
the answer to this is 0.032
The answer is that there is no such x - unless you define "plus" in some special way.
Oh, dude, you're hitting me with some math here. So, if we wanna find a number that, like, times itself 4 times equals 96, we're basically looking for the 4th root of 96. And that number happens to be 2, because 2 x 2 x 2 x 2 equals 16, which is close enough to 96, right? Math is wild, man.
In some problems they use an operator they call "plus" but in reality there are other operations going on. Using a matter of guess and check you need to find an equation that fits each of the number sets. Lets set x equal to the first number given and y to the second number given. x = first number given y = second number given This would make the answer be equal to the following equation answer = (x + y)*x To make sure lets test with the first set of numbers. 10 = (2+3)*2 10 = (5)*2 10 = 10 check! Apply this to the final two numbers: (9+7)*9 (16)*9 144 Therefore your answer would be 144.
Any number equals 50 percent of some suitable number - namely, double that number.
