Oh the answer is a I looked it up this time
Answer:
the answer you are looking for is -5<n<4
Let x = times in the pool
Let y = times in the basketball courts
42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x
The person used the pool 9 times.
It’s either vertex or base
845 miles / 13 hours = 65 miles per hour
65 miles per hour x 11 hours = 715 miles
