So basically, these numbers have to be consecutive because they're facing pages.
So you can just divide this by 2, and then add one to the second number.
629/2 = 314 R1
So the first page number is 314, and for the second one, just add one, and you get 315.
First you do $33.00/4 to get $8.25. Take the 8.25 and multiply it by 7 to get $57.75
Answer:
D. 
Step-by-step explanation:
Firstly, we know it's close to 6.75, so we can compute 6.75*6.75 and the product should be close to whatever's under the
. 6.75*6.75 = 45.5625, so we can already answer.
We could also figure out why other answers are bad.

Answer:
A and D
Step-by-step explanation:
A) 10+2^3*4-1 D) 10+(2^3*4)-1
10+8*4-1 10+(8*4)-1
10+32-1 10+32-1
42-1 42-1
41 41
