Answer:
The equation to determine the total length in kilometers is 
The total length in kilometers of Josh’s hike is 38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;

Hence, The equation to determine the total length in kilometers is 
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;

Hence, The total length in kilometers of Josh’s hike is 38 km.
Answer:
first equation : 3y + 6×=12
second equation : 4y + 8x = 16
Step-by-step explanation:
first equation
3y + 6× = 12
now take the common ,
3( y + 2x ) = 12
so, y + 2x = 4
second equation
4y + 8x = 16
4 ( y + 2x ) = 16
so, y + 2x = 4
two lines with same equation have infinitely many solution . these two equations are the same so there are infinitely many solution .

S8=64
Answer:
80.66
Step-by-step explanation:


Since we have three variables,



Therefore:

Using the above:
f(4.02, 3.99, 6.97) =81+ 8(4.02 - 4) + 8 (3.99 - 4) +14(6.97-7)=80.66.
The approximation of
is 80.66000.
