Answer:
i believe its c.) directly proportional.
Step-by-step explanation:
To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains
He would probably have to walk the dog seven more times
Answer:
No solution
Step-by-step explanation:
8x + 8 = 8x + 27
You then cancel out the 8s. 8 - 8 = 0
Which leaves you with 8 = 27...
Since this is an untrue statement, the answer would be no solution, unless you typed it wrong.
