Math each whole number with a rational,exponential expression

Pllz me also i will report if you are in for the 1. complete the table by converting each decimal to a fraction. repeating decimals. 0.31 0.125 0.1607 2. describe any patterns you noticed when converting the decimals in the table above.

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
