4.5x+7.05y=$43.65
x+y=8
Timed 4.5 for both side to get
4.5x+4.5y=36
4.5x+7.05y=43.65
-
4.5x+4.5y=36
=
2.55y=7.65
y=3 pounds
x=5 pounds. Hope it help!

Answer:
1/4
Step-by-step explanation:
The slope of a line is the steepness of a line.
The slope of a perpendicular line is always the negative reciprocal of the slope of the line it is perpendicular with.
Since line C has a slope of -4, the negative reciprocal of that is 1/4.
Reciprocals are two numbers that multiply together to get 1.
For example, -1/4*-4/1=1
Therefore the negative recipricol is 1/4
