Answer: C) 2 dimensions; flat surface of length and width, but no depth
One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.
6 - x = 2(x - 6)
the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer
Answer: The third one or C
Step-by-step explanation: That is the correct distance formula.
To solve this we can make it into an equation, which looks like this
y = 2x (for Rebecca)
y = x + 10 (for Alice)
The we subtract one equation from the other to solve
0 = x - 10
10 = x
x = 10
Now we replace x in whichever equation and we get 20
So, each girl will read 20 books for them to be at the same book.
