Let the number be represented by x. The equation representing the given scenario is 2x + 13 = 38. To solve for x, we first subtract 13 from both sides to isolate the term with x, giving us 2x = 25. Finally, dividing both sides by 2 gives us x = 12.5. Therefore, the number is 12.5.

A natural number is doubled when added to its reciprocal. Find that number!

Let the number be ( x ). According to the problem, when 8 is added to ( x ), the sum is doubled: [ 2(x + 8) = x - 11 ] Expanding and rearranging gives: [ 2x + 16 = x - 11 \implies 2x - x = -11 - 16 \implies x = -27 ] Thus, the number is (-27).
