a) Slope = 1 hour / 3 kilogram = 20 minutes per kilogram.
b) 20 minutes x 4 kilograms = 1 hour and 20 minutes total
Answer:
![W=\dfrac{P}{2}-L](https://tex.z-dn.net/?f=W%3D%5Cdfrac%7BP%7D%7B2%7D-L)
Step-by-step explanation:
![P=2L+2W \qquad\text{given}\\\\P-2L=2W \qquad\text{subtract $2L$}\\\\\dfrac{P-2L}{2}=W \qquad\text{divide by 2}\\\\W=\dfrac{P}{2}-L \qquad\text{carry out the division}](https://tex.z-dn.net/?f=P%3D2L%2B2W%20%5Cqquad%5Ctext%7Bgiven%7D%5C%5C%5C%5CP-2L%3D2W%20%5Cqquad%5Ctext%7Bsubtract%20%242L%24%7D%5C%5C%5C%5C%5Cdfrac%7BP-2L%7D%7B2%7D%3DW%20%5Cqquad%5Ctext%7Bdivide%20by%202%7D%5C%5C%5C%5CW%3D%5Cdfrac%7BP%7D%7B2%7D-L%20%5Cqquad%5Ctext%7Bcarry%20out%20the%20division%7D)
This formula does not seem to be among the answer choices.
W = (P/2) -L

So the total cost (C) would be equal to the standard charge (S) plus the insurance charge (I). You would plug in the numbers for each into an equation C= S + I.
Unfortunately, I do not understand the numbers given in the equation. There should be a variable for m (the number of miles driven). Although there is an m in the question, the numbers in front of it for the standard charge or insurance do not make sense to me. =I+5.700.25M and
=S+18.950.40M.
Example:
If I was 5.7 + 25m and S was 18.95 + 40m, the equation would look like:
C= S + I
C= 18.95 + 40m + 5.7 + 25m
C= 65m + 24.95
Thanks for asking for my help! Sorry I could not be of more help for you!! :(
X+x+x+x would just be 4x because there are 4 x's
