THE BEAUTY OF MATHEMATICS (Part 1)
Do you know that?.... According to Wikipedia, Mathematical beauty describes the notion that some mathematicians may derive aesthetic pleasure from their work, and from mathematics in general. They express this pleasure by describing mathematics (or, at least, some aspect of mathematics) as beautiful. Mathematicians describe mathematics as an art form or, at a minimum, as a creative activity. Comparisons are often made with music and poetry. Do you also know that?....
4(a) + 2(b) = 74
ReplyDeletea+b=30
4(30-b)+2(b)=74
120-4b+2b=74
120-74=4b-2b
2b=46
b=23 (Chickens)
Solve for a
4(a)+2(30-a)=74
4a+60-2a=74
4a-2a=74-60
2a=14
a=7 (cows)
