Let the smaller number be x.

The larger number is 1 more than 3 times the smaller number; in numbers this is: 3x + 1.

Their sum is 15, so subtracting x from 3x + 1 will be equal to 15. Your equation is: 15 = (3x + 1) - x

Solve 15 = (3x + 1) - x algebraically for x, and then plug x into 3x + 1 to find the larger number.

15 = (3x + 1) - x
15 = 3x + 1 - x
15 = 2x + 1
14 = 2x
7 = x

3x + 1
3(7) + 1
21 + 1
22

Finally, check all work.

22 - 7 = 15
7(3) + 1 = 22

Answer:
The smaller number is 7 and the larger number is 22.

According to his car odometer,Alfonso drove a total of 10 kilometers from his house to the movie theater and back again approxim
Brums [2.3K]

Answer:

It is approximately 3.10 miles from Alfonso's house to the movie theater

Step-by-step explanation:

First, identify what you know:

1) Alfonso drove from his house TO the movie theater, and then BACK to his house.

2) Alfonso's odometer shows him that the ENTIRE trip was 10 miles.

If the entire trip was 10 miles, and he only went to the move theater, AND took the same route back, then we simply divide 10 in half! This will give us the distance from his house the the movie theater, or rather, half of the trip, in kilometers.

10/2 = 5 kilometers.

Now, what is 5 kilometers in miles? Well, one mile is equal to 1.60934 kilometers, and one kilometer is equal to 0.621371 miles. So, simply multiply!

5 km  x 0.621371 miles = 3.106855

The approximate distance from his house to the theater is 3.10 miles!

Hope this helps! :)
