Answer:

CD = 45

Step-by-step explanation:

CE = 180

( x + 6 ) + ( 4x - 21 ) = 180

5x - 15 = 180

5x = 195

x = 39

substitute x in CD

CD = x + 6

CD = 39 + 6

CD = 45

Isaiah will mow 9 lawns in 3 hours at the given rate.

75 lawns = 25 hours

1 lawn = $\frac{25}{75}=\frac{1}{3}\ hour$

9 lawns = $\frac{1}{3}*9$

9 lawns = 3 hours
