Answer:

Step-by-step explanation:
We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.




Now we can plug the value of
back into the expression we were given for the line KL.


Answer:
90m+145
Step-by-step explanation:
80 + 50m + 65 + 40m
90m+145
(-2,4), (2,5)
Slope equation : (y₂-y₁) / (x₂-x₁)
Plug in the values.
m = slope
m = (5-4) / (2 + 2)
Simplify.
m = 1/4
So, your slope is 1/4

Answer:
The answer is C.
Step-by-step explanation:
In order to find the value of m, you have to eliminate -10 on the right side by adding 10 to both sides :
8 = -10 + m
8 + 10 = -10 + m + 10
18 = m
m = 18
