3x + 11
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
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.
Any number equals 50 percent of some suitable number - namely, double that number.
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.
30 some thing
A number plus zero equals the original number. A number minus zero equals the original number. A number multiplied by zero equals zero. A number cannot be divided by zero. Zero is the only number that is neither positive nor negative. Zero represents the boundary between positive and negative numbers. Zero is the natural starting point on many scales, such as on thermometers. Zero is the common point of coordinate axes.
