95. ## Algebra

It's been a while since I've had to do this so I don't remember. I have the equation 6x + 19 = x. They want me to solve for x. I'm guessing I have to move over 19 to make it the sum, but how do I do that?

96. ## Chemistry

Use the henderson-hasselbalch equation to predict the change in pH when 0.50ml of 1M HCl is added to 40mL of .10M buffer at pH 6 and pH 7.5. My two solutions are Na2HPO4 and NaH2PO4.pKa=7.2 Now I don't even know where to begin and how to use the equation.

97. ## Trigonometry

Use inverse trigonometric functions to find the solutions of the equation that are in the given interval, and approximate the solutions to four decimal places. (Enter your answers as a comma-separated list.) cos(x)(9cos(x) + 4) = 4; [0, 2π)

So we prepared 100mL of .1M solutions of these solutions, and found the pH and H+ contents: pH H+ HCl: .57 .270 HNO3: .58 .260 H2SO4: 1.29 .051 HC2H3O2: 2.44 .0036 H2C2O4: .84 .145 HKC6H4(CO2)2: 4.13 7.41 Now I'm stuck on this question. What conclusions
