The answer would be t=20n or something similar because 20n stands for $20 per lawn, which equals t, the total.
of a 90 degree angle, and two other angles that all should add up to 180 degrees.

Answer:
Step-by-step explanation:
if the lines are parallel they have the same gradient.
rearrange the equation to make y the subject and then use the m value as gradient.
-3x=2-y
-3x-2=-y
y=-(-3x-2)
y=3x+2
therefore m=3
slope is 3
