Well, when it comes to math, I gotta admit, I'm not the smartest cookie in the cookie jar, but if you take 20 2/5 and divide it by 2/5, you should be left with the number of sheets of sheetrock there are in the stack. To divide it, you my have to convert the fraction to a decimal, just FYI. Considering this is marked as a college-level question, I assume you already know how to do this. Hope this helps ya, pal.
Answer:
482.7972
Step-by-step explanation:
It would be y=3x+2 because in y=mx+b, m is the slope and b is the y-intercept
Start by distributing -5x into x then into -3y. So -5x times x equals -5x^2( -5x squared), then -5 times -3y, equals 15xy so your answer is -5x^2 + 15xy.
