To Euclid, a postulate is something that is so obvious it may be accepted without proof.
A. A straightedge and compass can be used to create any figure.
That's not Euclid, that's just goofy.
B. A straight line segment can be drawn between any two points.
That's Euclid's first postulate.
C. Any straight line segment can be extended indefinitely.
That's Euclid's second postulate.
D. The angles of a triangle always add up to 180.
That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."

Final answer:
To find the number of 4th graders at school on a day when 15 were absent, subtract the number of absent students from the total number of students. In this case, the answer is 89.
Explanation:
In Allison's school, there are 104 students in the fourth grade. One day, 15 fourth graders were absent. To find out how many fourth graders were at school that day, you would subtract the number of absentees from the total number of students:
Step 1: Start with the total number of students, which is 104.
Step 2: Subtract the number of absent students, which is 15.
The calculation should look like this: 104 - 15 = 89. So, there were 89 fourth graders at school that day.
To find the number of 4th graders at school on the day 15 were absent, subtract the number of absent students from the total number of students. In this case, there are 104 students in the 4th grade and 15 were absent, so the number of students at school that day is 104 - 15 = 89.

Remember that subtracting a negative number is the same as adding a positive number, so...
-6-(-8)=-6+8
-6+8=2
Since the answer, 2, and the addends, -6 and 8 fall in between -10 and 10. The number line will suit the problem. They are also all even numbers so if the labels are in intervals of 2, it will be easily read.
Hello,
