AI Thread Summary
Bob's current savings can be represented as $x$. If he had $150 more, his savings would be $x + 150$. This amount is stated to be five times his current savings, leading to the equation $x + 150 = 5x$. Solving this equation reveals that Bob currently has $37.50 saved. The discussion emphasizes the importance of accurately framing mathematical problems for clarity.

Re: Having some troubles.

Suppose currently Bob has $x$ dollars in his saving account. Write the following quantities using $x$.

  1. \$150 more than what Bob currently has in his saving account.
  2. Five times as much as Bob currently has in his saving account.

Then equate 1 and 2 and get an equation in $x$.
 
Hi lmae. I've edited the title of your thread to more accurately reflect the nature of the problem. In future, please try to do the same. Thanks. :)
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
