When Imani walks to school, it takes her one less minute than five times the amount of time it takes her to ride her bike to sch
zmey [24]

The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.

<h3>How do we derive a numerical expression?</h3>

Let:

x = amount of time it takes Imani to walk to school

y = amount of time it takes Imani to ride to school = 3 minutes

The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:

x = 5y - 1

Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:

x = (5 * 3) - 1 = 15 - 1 = 14 minutes
