Looks like you might have a typo there. Total number of coins = 35 Number of dimes = x Number of nickels nickels = 35 - x Value of 1 dime = 0.10 Value of 1 nickel = 0.05 0.10x + 0.05(35 - x) = 3.30 0.10x + 1.75 - .05x = 3.30 0.05x = 1.55 x = 31 dimes 35 -...

2y<sup>2</sup> + 8y - 24 = 0 2(y<sup>2</sup> + 4y - 12) = 0 2(y + 6)(y - 2) = 0 (y + 6) = 0 (y - 2) = 0 y = -6 y = 2

The ideal gas law is PV = nRT. You have n (2.80mol), V (18L), and T (24°C). R is the universal gas constant (which equals 0.0821 L* atm/mol * K). Convert Celsius to Kelvin: 24°C + 273K = 297K insert the numbers into the equation: P(18L) = (2.80mol)(0.0821...
