First we need to know what number 2*5*7 gives us. That's the same as 10*7=70. So the question is asking how many multiples of 70 are between 1 and 700. Let's list them:
70
140
210
280
350
420
490
560
630
700
So there are 10 integers from 1 to 700 that are divisible by 2, 5, and 7.
5x-2=3x+8
X=5
That's your answer
12,925
The nearest number right before the ten thousandths place is a 2. So you round down to get 10,000.
