My best physical measurement is 1.81 with a surface plate, precision balls and a height gauge, but I can't mathematically back it up with the correct answer. Help? My first atte...

What is the meaning of "prime n", "prime 1", "(prime n) - 6", and "(prime 1) - n"?

Kindly please include, within your reply, a complete statement of your efforts thus far. Thank you.

1/4(x+2) <= -3/4(x-2) By adding +3/4(x-2) I simplify to (x+1)/(x^2 - 4) By what steps did you obtain this result? (Your formatting is ambiguous. Are the variable factors in the numerators or in the denominators?) a) if I solve the same inequality by cross multiplying.... By what logic have you &quo...

So I've actually gotten pretty far but I'm stumped here: \frac{3}{2}\frac{y-x\frac{3x}{2y}}{y^2}=\frac{3(2y^2-3x^2)}{2^2y^3} I guess I'm getting stumped by the algebra here. How did they go from the left side of the fraction to the right side? What were your results, upon attempting to simp...
