Answer: 20 lawns</h3>
Work Shown:
8 lawns = 2 hours
4 lawns = 1 hour (divide both sides by 2)
20 lawns = 5 hours (multiply both sides by 5)
A = lw
Plug in what we know:
25/54 = (5/9)w
Divide 5/9 to both sides or multiply by its reciprocal, 9/5:
25/54 * 9/5 = w
Multiply the numerators and denominators together:
225/270 = w
Simplify:

Answer: -2
Explanation: The coefficient is the number to the left of the variable.
Another example would be that 10xy has the coefficient 10.
Something like x^2 has coefficient 1 because x^2 = 1x^2.
