Answer:
2(4ax+2bx+2a+5b)
Step-by-step explanation:
Answer: No it’s not.
Step-by-step explanation: So if to find the next number, you add five, then all of the numbers in the sequence will either end with 8 or 3. (5+3 or 0+3). Therefore 97 is not a term in the sequence.
I find the problem confusing because it forces a certain sequence of thought process, and I find I get way beyond these questions and answers rather quickly. I would start with the equation of part B, having already recognized the conversions of percent to decimal and the need to make the acid quantities add up. Doing the problem a different way gets you to the answer in part C without any of these "steps," so going back and trying to fill in the "steps" seems awkward, at best.
