x=23-2y
y=4-2z
x=23-8+4z
x=15+4z
z=-6-2x
z=-6-30-8z
9z=-36
z=-4
x=-1
y=12
x+y+z=-4 + -1 + 12 = 7
5.) D
The largest interger less than 350,000 is 349,000, but 9 is outside the parameter of digits 2 -7. thus the next highest is 347,652
7.) A
Since the cycle consists of 5 numbers, take 206 and divide by 5, and whatever the remainder is your the sequence of your number. In this case, the remainder is 1, so take the first number in the sequence. which is 1.
209 divide by 5 gives you remainder of 4, so the 4th number in this sequence is 7. now you add everything in between, you get 1+3+5+7=16, average is 16/4 = 4
10.) 42%
Take X as your total number of books. hard covered books are 60% of X, so its .6x
30% are leather, so it means 70% are not leather. so you take 70% of .6x which is .42X = 42% of the all the books
12.) D
I am assuming | | is an absolute value sign.
4 – 3 |10-8 | =
4- 3(2) =
4 – 6 = -2
