ANSWER:
its $45
Step-by-step explanation:
add it all together...easy
18 - (-f) = 91
Subtracting a negative value changes to addition:
18 + f = 91
Subtract 18 from both sides:
F = 73
The answer would be 6b-3c because a would cancel out and be 0
A is the correct answer. A coefficient is just a number that appears in front of a variable. Please note that a number that doesn't have a variable behind it is still a coefficient since there is technically a variable behind it with a power of 0.
