Annette [7]

Using the relation between velocity, distance and time, it is found that the commute took 48 minutes.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is distance divided by time, that is:

v = \frac{d}{t}

For Lena, we have that d = 29, v = 36, hence the time in hours is given by:

t = \frac{d}{v} = \frac{29}{36} = 0.8056

In minutes, the time is given by:

tM = 0.8056 x 60 = 48.

During a sale a dress decreased in price from $60 to $48 what was the percent of decrease
Elza [17]

Answer:

The percent decrease was 20%

Step-by-step explanation:

In order to find this, use the percent change equation.

(New - Old)/(Old) * 100 = % Change

Now input 48 for the New price and 60 for the Old price.

(48 - 60)/(60) * 100 = % Change

12/60 * 100 = % Change

.2 * 100 = % Change

20 = % Change

How many solutions can be found for the equation 4z + 2(z - 4) = 3z + 11
Gnom [1K]
4z+2(z-4)=3z+11  perform indicated multiplication on left side

4z+2z-8=3z+11  combine like terms on left side

6z/-8=3z+11  add 8 to both sides

6z=3z+19  subtract 3z from both sides

3z=19  divide both sides by 3

z=19/3 

z=6 1/3

So there is only one solution when z=6 1/3
