Question: Are pages 51-55 missing answers?
Answer: No, they are not. Pages 51-55 are the introduction of Chapter 3, which includes instructions and examples. There are no exercises on those pages.
Question: Should the answer to page 56, problem 9 be squareroot(7/5)?
Answer: Actually, that's the same as the answer listed if you rationalize the denominator.
Question: Could you please check the answer to page 32, exercise 5?
Answer: Even better, I will work out the solution for you so that you can follow along.
- -x/5 - 3x/2 = -x/5 + 5/3
- Add x/5 to both sides to separate the variable terms (with x) from the constant term (5/3).
- -3x/2 = 5/3
- Multiply both sides by 2.
- -3x = 10/3
- Divide both sides by -3
- x = -10/9
- The answer listed in the back of the book is -10/9. You can also verify this answer with an online algebra solver, such as Mathematica offers.
If these professionals would understand the NEED for science based treatment for this population - what changes we would see.
Buy this book - give yourself the power to make an informed decision - you deserve that - your child deserves nothing less than that.. It is especially helpful for those (children and adults) who are learning keyboards, harps, or beginning band instruments. She loves this diet. I especially appreciate her in-depth analysis on the various biomedical approaches to autism treatment, which are great inoculations for parents who might wonder if they should re-mortgage their house to buy a hyperbaric oxygen chamber, spend money on expensive vitamins or hormone treatments, or forbid their child from ever eating normal food again. If you have already put Zora on a Pedestal, then you may not want to read this book as it shows his human side (but does not tarnish it). More than a few fist-pumping moments and laugh-out-loud parts catch you off guard while the ma
