Name Date Period Solve each equation. Classwork. 1. An inlet pipe can fill a tank in 3 hours. It takes 11 hours for the drain pipe to empty the tank. How long will it take to fill the tank if both the inlet pipe and the drain Fill pipe are open?HT CUD 3 20 (x/5 + x/11 = 1) 53 4 1/8 * h omega cw 2 Emph 11 (1) * x - bx = 33 8x33 2. The amount of money earned on a job is directly proportional to the number of hours worked. If $36 is earmed for 8 hours of work, how much is earned for 30 hours of work? E = kh 36 = k * 8 E = 4.5h E = 4.5(3nu) xi = 135 $135.00 3. The variables x and y vary inversely, and that relates x and y, find y when x = - 3 y = k/x y = 3/x y = 1/2 when x = \mathfrak{b} Write an equation 1/2 = k/6 3 = k y= 3 3 | y = - 1 4. The time, i, required to do a certain job is inversely proportional to the number of people, n, working. Write an equation ift t = 15 when n = 6 t = k/n 15 * k/6 90ck t - 90/n current in an electrical circuit varies inversely as the amount of resistance in the circuit. The current is 10 amps when the resistance is 24 ohms. Find the current when the resistance is 30 ohms. C - k/r k = 240 C = (24v)/r C = 240/40 C = 8 otimes a np 6. Three fourths of a number is as, the original number increased by one, and all divided by two. x = 4(x - 4) 6x - 4x - 4 chi_{2} 3/4 * x = (x + 1)/2 1ong H = 2 7. ∞ * x = 4 One integer is 2 less than integer. Three times the reciprocal of the lesser integer plus five times the reciprocal of the greater integer is integers? 7/8 What are the two Qua X - 2 3(1/(x - 2)) + 5(1/x) = 7/8 ) 3/(x - 2) + J/x = 7/8 )^ 8x(x-2) 74x ne 40(x - 2) = 7x(x - 2) 0 = - 7x = 78x + 80 0 = (7x - 8)(x - 10) x = 7/7 1x <10? 1108 A
