We can rearrange this to the reverse operation, which should yield 96x + 1 = 289.Subtract 1:288 = 96xDivide by 96:288/96 = 3 = xx = 3, which should be the answer.
After the IUPAC tables from 2009 the atomic mass of ununpentium is [289].

They are equal.Work:8 yards x 36 inches per yard = 288 inches
137 plus 149 plus 162 plus 201 plus 217 plus 289 plus 372 = 1,527
No - rounded to two decimal places, sqrt(288) is equal to ±16.97. However, the integer one greater than this, 289, is equal to 17 squared.

There is no solution. For two numbers to add to an odd total, one of them must be even. If that number is also a prime it must be 2. But if one of the numbers is 2 and the two sum to 289, the other must be 287. But 287 is not a prime and the question required two primes to be added.
No, 288 is, but 289 is not. For a number "x" to be divisible by 4, "x" must be even, and "x/2" must be even as well. 289 is not even. ■ To check whether or not the number is divisible by 4 it is enough to check (as above) that the last two digits of the number are divisible by 4. In this case, it would be to check that 89 is divisible by 4.
