Answer:
Start by distributing the 15 to the (m-1). 9+12m=6+15m-15. Then combine like terms. 9+12m=15m-9. Next move the variable all to one side, it doesn't matter which variable you choose. I'll use 12m so when I subtract I am still left with a postive coefficient. To move the 12m we subtract it from both sides of the equation. We are left with 9=3m-9. Next we isolate the m by canceling out the 9. We do this by adding 9 to both sides. We are left with 18=3m. Finally, to completely isolate the m, we must divide both sides by the coefficient, 3. The result is 6=m. The answer is 6 months. You can check this by plugging 6 back into the equation where there is an m. (sorry for the long answer)
Step-by-step explanation:
Here is the graph equivalent
If the snow falls at a rate of 1.3 inches per hour, dividing 6.825 into 1.3 should give you your answer.
6.825/1.3 = 5.25
Therefore, the snow was falling for 5.25 hours, or 5 hours and 15 minutes.
Umm i think every one = 6
