⦁ Use both methods to find the distance between the points on the number line.
Vitek1552 [10]

Answer:

4 and 4

Step-by-step explanation:

Method A

1) Method A: Let 2 be the starting point and -2, the finishing one. Counting between 2 and -2, we can count a distance of 4 units. That's the simplest way, but not convenient to great numbers on the Number Line.

Method B:

There is no such thing as a negative distance, as a physical quantity. So this is the reason why we need to compute the absolute value of two numbers, which is simply what was done on Method B.

|2-(-2)|=|4|=4

As we are dealing with absolute values, the order is not relevant after all, the result remains the same. Take a look:

|-2-2|=|-4|=4

That's why the greater (2) or the lesser number (-2) can be the subtrahend (in bold within the brackets.

Which statements about angles are true? Check all that apply.
Vadim26 [7]

Answer:

A,C,D,E

Step-by-step explanation:

The first one is true because in fact, supplementary angles' measures add up to 180°.

The second one is false because there are 5 types, not 3. These are the types:

acute angle-an angle between 0 and 90 degrees.

right angle-an 90 degree angle.

obtuse angle-an angle between 90 and 180 degrees.

straight angle-a 180 degree angle.

reflex angle- a angle between 180 and 360 degrees.

Third is true too because linear pair means two angles that form a straight line, or 180°.

Fourth is true because straight Angle theorem states that all the straight angles are 180 degrees. If the legs are pointing exactly in the opposite directions, then it forms a straight angle.

Last one is true because by definition complementary angles always form a right angle, which is 90°.

Hope it helps!
