Gina started hiking down a mountain trail at the same time that melissa started hiking up the trail. melissa's elevation is represented by the equation h = 2 + t, and gina's elevation is represented by h = 9.5 – 1.5t, where t represents the number of hours they have been hiking. what point represents the time, in hours, since they started hiking and the elevation where melissa and gina meet on the trail?

point (3,5) represents the time in hours  , since they started hiking and the elevation where Melissa and Gina meet on the taril.

Step-by-step explanation:

Given , Gina started hiking down a mountain trail and Melissa started hiking up the trail at the same time.

Melissa's elevation is represented by the equation

Gina's elevation is represented by the equation

Where t= Number of hours  for hiking

h= Elevation

In this method we equate the coefficient of any variable h or t and then subtract one equation from  other equation and we get value of h or t  then put the value of h or t in  any equation and get the value of  other variable .

Now , by using this method subtract Melissa's elevation  equation from Gina's elevation  equation then we get

we get ,

Now, put the value of t in Melissa's equation then we get value of h

Hence, time,t=3 hours and elevation, h= 5

Therefore, the point is (3,5)  represents the time ,in hours ,since they started hiking and the elevation where Melissa and Gina meet on the trail.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
