Answer:Corey was travelling at 9 miles per hour and Tom was travelling at 13 miles per hour.
Step-by-step explanation:
Let x represent Corey's speed.
If Tom travels 4 mph faster than Corey, it means that Tom's speed would be (x + 4) mph
Corey is 176 miles from Tom and they are traveling towards each other. If they meet after 8 hours, it means that they travelled a total distance of 176 miles in 8 hours.
Distance = speed × time
Distance travelled by Corey in 8 hours would be
8 × x = 8x miles
Distance travelled by Tom in 8 hours would be
8(x + 4) = (8x + 32) miles
Since the total distance travelled by Tom and Corey is 176 miles, then
8x + 8x + 32 = 176
16x = 176 - 32 = 144
x = 144/16 = 9 miles per hour
Tom's speed would be
9 + 4 = 13 miles per hour
So you would do
5×4×3= 60
and
5×4=20
so, for a 3 digit code there are 60 possibilities and for a 2 digit code there are 20 possibilities.

Answer:
640 foxes
Step-by-step explanation:
The actual formula is 
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
Finally, we can see that there should be 640 foxes after 26 years.
