You can put this solution on YOUR website! Let x be the amount of 10% mix to be drained and replaced with 100% antifreeze. For every x quarts drained, that drains 0.10*x quarts of (pure) antifreeze. Note that we want 8 quarts *0.2 = 1.6 quarts of antifreeze in the final mixture. And, we start with 8*0.1 quarts of antifreeze. —

You can put this solution on YOUR website! Let x=amount of pure alcohol needed Now we know that the amount of pure alcohol added (x) plus the amount of pure alcohol in the 5 liters((0.15)*5) has to equal the amount of pure alcohol in the final mixture ((0.25)*(5+x)). So our equation to solve is: x+0.15*5=0.25(5+x) get rid of parens and simplify

Answer by drk (1908) (Show Source): You can put this solution on YOUR website! I think you want help solving for d in the following equation: 11=-d+15. 11=-d+15. step 1: -15 from both sides, you want to isolate the variable. This gives us -4 = -d. step 2: divide both sides by -1. This gives us 4 = d.
Question 631629: (x+y+z)^3 Answer by lenny460 (1073) (Show Source): You can put this solution on YOUR website! (x+y+z)^3 (x + y + z) (x + y + z) (x + y + z) We multiply using the FOIL Method: x * x = x^2 x * y = xy x * z = xz y * x = xy y * y = y^2 y * z = yz z * x = xz z * y = yz z * z = z^2 We now have: x^2 + xy + xz + xy + y^2 + yz + xz + yz ...
You can put this solution on YOUR website!. From this point, you need to solve this equation s + = 4400. Let u = be new variable. Then your equation (1) takes the form u^2 + 275u = 4400, or, equivalently, u^2 + 275u - 4400 = 0. Apply the quadratic formula = = . You are looking for positive solution "u", so, you accept the positive value, only ...
