Determine which of the given pairs are larger: 1. 5+t^2 & 3-t^2
2. 15/x^2+6 & 15/x^2+7
3. (s^2+2)(s^2+1) & (s^2+4)(s^2+3)
4. 8/k+2 & k^2+2

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
