-5x+4y-7x-9y
-12x-5y
12x+5y=I
Dameon's answer should be closer to $0.40 as the real cost is $3.88 per rubber pad
You can find this by $465.60 by 120
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
The right answer is C) 70 miles.
3x=6 is the answer after solving the first step in the equation
