Answer:
530,000
Step-by-step explanation:
The equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.
The total distance that Joe needs to cover to travel to Dallas = 320 miles {As he lives 320 miles away from Dallas}.
The distance that Joe covers after traveling for h hours at an average speed of 69 miles per hour = 69h {as Distance = Speed*Time}
Therefore, the distance left to cover by Joe, that is the distance from Dallas d can be written as the difference between the total distance needed to be covered and the distance Joe already covered.
Thus the equation is d = 320 - 69h.
Thus, the equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.

36+20=56
Voila!
I thought about this for a while and then recognized that this number is possibly divisible by {3, 4, 6, 8, 9, 10, 12, etc.}
So I look for possible sets of 3 numbers here that add up to 18. The first such set I recognized was {4, 6, 8}. These digits do add up to 18. Unfortunately, 468 is not in the desired range (600,700).
Thus, I could try either {6, 4, 8} or {6, 8, 4}.
There may be other combinations of 3 numbers (which must add up to 18).
Test 684. Is 684 between 600 and 700, not including 600 or 700? YES.
Is the sum of {6, 4, 8} equal to 18? YES. So, 648 is one possible answer. Are there others?
