AI Thread Summary
To solve the problem of determining how many high-quality songs were downloaded, a system of equations is suggested. The first equation is based on the total size of the downloads: 2.3S + 4.2H = 4077, where S represents standard versions and H represents high-quality versions. A second equation is needed, which can be derived from the total number of downloads: S + H = 1120. By solving these two equations simultaneously, the number of high-quality songs downloaded can be calculated. This approach provides a structured method to tackle the word problem effectively.

My homework question is "the standard version of a song is 2.3mb and high quality is 4.2mb. There was 1120 downloads for a total of 4077mb. How many high quality songs were downloaded?" I'm having an issue creating the formula needed to solve this word problem!

Hi reader1018,

I think we can set up a system of equations to solve this. Let's call $S$ the number of standard versions downloaded and $H$ the number of high quality versions downloaded. We are told that $2.3S+4.2H=4077$. We need a second equation though to solve for both variables. What else do we know?
 
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...
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...
