L = 8 + T
L = 2T
You can combine them
2T = 8 + T
T = 8
If Tim walked 8, Lisa walked twice as much which is 16
The amount of pens he buys affects the amount he spends. (not vice versa)

That point will be where the perpendicular line through the origin intersects the given line.
.. (-1/4)x = 4x +3
.. -3 = (17/4)x
.. -12/17 = x
The point on the given line that is closest to the origin is (-12/17, 3/17).
Answer:
w + d = 797
w = d - 53
Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.
d - 53 + d = 797
2d = 850
d = 425
Step-by-step explanation:
The correct answer is 54.3.
