Answer:

1)(2m^2-4m)/2(m-2) = m (fourth blank)

2)m^2-2m+1/m-1= m-1 (second blank)

3)m^2-3m+2/m^2-m= (m-2)/m (first blank)

4)m^2-m-2/m^2-1=(m-2)/(m-1)    (third blank)

Step-by-step explanation:

1)

(2m^2-4m)/2(m-2)

=[2m(m-2m)]/2(m-2)

= 2m/2

=m

2)

m^2-2m+1/m-1

= (m-1)^2/(m-1)

=(m-1)(m-1)/(m-1)

=(m-1)

3)

m^2-3m+2/m^2-m

=m^2-m-2m+2/m(m-1)

=m(m-1)-2(m-1)/m(m-1)

= (m-1)(m-2)/m(m-1)

=(m-2)/m

4)

m^2-m-2/m^2-1

=m^2+m-2m-2/(m+1)(m-1)

=m(m+1)-2(m+1)/(m+1)(m-1)

=(m+1)(m-2)/m+1)(m-1)

=(m-2)/(m-1) !

Since there is a sales tax of 6% which was equal to $820

Let the value be = x

6% of x = 820

(6/100)x = 820

0.06x = 820

x = 820/0.06

x = 13666.67
