Hi, all we need to do is to divide the number of brownies by the number of students, and we will get the amount of how many would each student get.
26/15 = 1,73 brownies per student.
Any two numbers, normally degrees, such as 10° and 170°, that add up to equal 180°
If you add positive 5 and positive 5, you'll get positive 10.
If you add positive 5 and negative 5, you'll get positive 0.
If you add negative 5 and negative 5, you'll get negative 10.
-5 + 5 = -5 + 5
5 + 5 = 5 + 5
- 5 + -5 = -5 + -5
Does that help your question?
