x + x+1 + x+2 = 39 where x is the number.

= 3x+3 = 39

= 3x+3=3 = 39-3 Isolate x

=3x = 36

=3x/3 = 36/3 DIvide for x

x = 12

Therefore, the smallest number is 12.

12 + 13 + 14 = 39

So least integer = 12

Knowing the first day Anna and Tamara stop for sightseeing and lost 2 hours of travel time and the second day, they gain 1 hour
ratelena [41]

The algebraic expression that represents the number of hours Anna and Tamara traveled the first two days is (2x - 1) hours.

<h3>How to write Algebraic Word Problems?</h3>

We are told that;

On the first day, Anna and Tamara stop for sightseeing and lost 2 hours of travel time.

On the second day, they did not stop for lunch and gained 1 hour.

Now, we are told that x is the number of hours driven per day. Thus, for two days, number of hours driven is expressed as 2x.

Now, since they lost 2 hours on the first day, then total hours travelled is;

2x - 2 hours

On the second day, they gained 1 hour. Thus;

Final total number of hours traveled = 2x - 2 + 1

Final total number of hours traveled = (2x - 1) hours

Thus, we can conclude that the algebraic expression that represents how many hours Anna and Tamara traveled the first two days is (2x - 1) hours.

Miguel quiere entrenar para la carrera solidaria de verano en uno de los dos parques que tiene cerca de casa. Su plan es correr
kondor19780726 [428]

Answer:

  • <em>The square park is more convenient.</em>

Explanation:

The translation of the question is:

<em>Miguel wants to train for the summer solidarity race in one of the two parks that he has close to home. His plan is to run about 10 km each day and he wants to do an exact number of laps around the park to always start and end at the entrance. Since he has not quite decided between the square and the rectangular park, he decides to do some calculations to see which one suits him best.</em>

<em>Square park: 423 meters each side</em>

<em>Rectangular park: 673 meters measures the base and 218 meters the height</em>

<em />

<h2>Solution</h2>

<u />

<u>1. Calculate the perimeter of the square park</u>

The perimeter of a square is the sum of the four side lengths. Since they are equal it is:

  • Perimeter = 4 × side lenght
  • Perimeter = 4× 423m = 1,692 m

<u />

<u>2. Calculate how many times 1,692m is in 10 km</u>

10 km is 10,000 m. Then, divide 10,000 by 1,692 m:

  • Number of laps = 10,000m / 1,692m ≈ 5.91 laps

<u>3. Calculate the perimeter of the rectangular park</u>

  • Perimeter = 2×base + 2×height
  • Perimeter = 2×673m + 2×218m = 1,782m

<u>4. Calculate how many times 1,782 is in 10km</u>

  • Number of laps = 10,000m / 1,782m ≈ 5.61 laps

Then, since the number 5.91 is closer to an integer number than 5.61, you conclude that the square park is more conventient, because by running 6 laps around the square park the number of kilometers run will be closer to 10 km than with any number of complete laps in the rectangular park.
