Answer:
Monica will walk a total of 3km in 60 minutes given that she walked 1km in 20 minutes
Step-by-step explanation:
The correct question is given below;
Monica walked every day for exercise at a rate of 1 kilometer every 20 minutes. At this rate, how many meters can Monica walk in 1 hour? EXPLAIN how you found your answer
solution;
Now in this question, given the number of kilometers Monica walks in 20 minutes, we are now told to find the number of kilometers she will walk in 60 minutes.
Now to get this, the easiest way to this is to use a cross multiplication as follows;
1km = 20 minutes
xkm = 60 minutes
Kindly remember/ recall that in an hour we have 60 minutes so it is necessary to make the conversion to the unit to achieve consistency. You might want to convert 20 minutes to hours too , but it is better to have it in minutes
Now let’s make the cross multiplication;
1 km * 60 minutes = x km * 20 minutes
xkm = (1km * 60 minutes)/20 minutes
xkm = 60 km minutes/20 minutes
xkm = 3km

Answer:
294 cars.
Step-by-step explanation:
Let x be the number of cars and y be the number of trucks.
We have been given that the first dealership sells a total of 164 cars and trucks. We can represent this information as:
The second dealership sells twice as many cars and half as many trucks as the first dealership. So the number of cars sold by 2nd dealership will be 2x and number of trucks sold by 2nd dealership will be y/2.
Further, the 2nd dealership sold a total of 229 cars and trucks. We can represent this information as:
We can see that total number of cars sold on two dealerships will be 
.
We will use substitution method to solve for x. From equation (1) we will get,
Substituting this value in equation (2) we will get,
Now let us have a common denominator.
Upon multiplying both sides of our equation by 2 we will get,
Therefore, the total number of cars sold by two dealerships is 294.
For the first rectangle, you take 7ft x 4ft x 5ft which is equals to 140 ft^3.
For the second rectangle, you take 10 ft x 8ft x 6ft which equals to 480ft^3.
