As far as I understand A)
A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
9/8
Explanation: a perpendicular slope is the opposite of what the normal slope was before
C is the answer look at the way I. form is
737 X 74 = 54,538
Evenly divided by: 2, 11, and 22
