640,700 :- the four in this number is 40,000
67,040 :- the four in this number is 40
Now, we need to find out how many times greater 40,000 is than 40.
40,000/40 = 1000
Answer: It is 1000 times greater.
Answer: D) 10
============================================================
Explanation:
I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.
So,
DE = 2*(MN)
3x-2 = 2*(x+4)
3x-2 = 2x+8
3x-2x = 8+2
x = 10
Reduce the expression by cancelling the common factors: 1/n
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
The correct answer.would be A. because 100 x 10,000 is 1,000,000. You just need to round then multiply.
-I hope this helps you out. :)
