2 times 13 equals 26. 1 times 26 also equals 26.
3x + 11
2n = 24 n = 12
5*(3+x)=15+5x Fifteen plus five times that number
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.
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.
