Answer:
17/20
Step-by-step explanation:
To find the simplest form of 0.85 you need to turn it into a fraction.
To turn it into a fraction you put 85 over 100 since 0.85 is in the hundredths place.
85/100 can be simplified to 17/20 because 85/5 is 17 and 100/5 is 20
Solve for m by simplifying both sides of the equation, then isolating the variable.
m = -2.5
The answer is (-18, -2). Just multiply by 2!
It is C because a and b are zeros
