Chandler can mow 2 lawns per hour. use an equation to determine the number of hours it will take him to mow 7 lawns.

We can use the equation n/2 = h

n = the number of lawns Chandler mows.

h = the number of hours he spent.

Lets fill in for n since he mowed 7 lawns.

7/2 = h

3.5 = h

If you want to turn it into a timely fashion: 3.5 = 3 hours 30 minutes.

So, it took Chandler 3 hours and 30 minutes to mow 7 lawns.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
