The larger of two numbers is 5 more than the twice the smaller. if the smaller is subtracted from the larger, the result is 12. find the numbers.
i need this explained in the easiest way so i can understand. you.

Let is the smaller of two numbers. The larger of two numbers is equal to
If we subtract smaller number from larger, we get 12.

We have to solve this.


We get the smaller number.
The larger one:


Two numbers we are looking for are 7 and 19.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
