Answer: 
Step-by-step explanation:
1. You have the following phrase given in the problem: 16 times as many books. You can conclude this is a multiplication word problem, because:
- Let's call 
the number of books.
- "As many boooks" indicates multiplication.
- 16 times means that should be multiplied by 16.
2. Then, you can conclude that the expression that best represent the phrase is:
Red + green = 24; (1)
red + blue = 10; (2)
blue + green = 20; (3)
(1) - (2):
green - blue = 14; (4)
(3) + (4):
2 * green = 34;
green = 17;
Simple substitution gives:
blue = 3;
red = 7;
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
Answer: Each multiple choice question is worth 5 points.
Step-by-step explanation: You can find this answer by using the equation "14m + 24 = 16m + 14" and then solving for "m". To find what "m" is, you must first subtract 14m from both sides, leaving "24 = 2m + 14". Next, you subtract 14 from both sides, leaving "10 = 2m". Finally, you divide both sides by 2, which will give you "m = 5". Thus meaning each multiple choice question is worth 5 points.
To check this, simply fill in for "m" and solve each side. 14 * 5 + 24 = 94 and 16 * 5 + 14 = 94. 94 = 94, so "m = 5" is correct.
I hope this helps!
