Answer:
It helps you know if the answer is reasonable because when you do the work and get your answer, you can check if it is close to your estimate, and if it is, it is most likely correct. On the other hand if it is not close to the estimate it is most likely wrong, unless you estimated incorrectly.
Step-by-step explanation:
Answer: The greatest common factor is 6.
Step-by-step explanation:
18 goes into 6, 3 times
30 goes into 6, 5 times and q2 goes into 6, 2 times
Divide all three numbers by 6.
The new equation will look like: 3x-5+2y

A rotation is a rigid transformation, sometimes called an isometric transformation, that moves every point of the pre-image through an angle of rotation about the center of rotation to create an image. Rotations preserve size, rotations of 360 map a figure to itself, and lines connecting the center of rotation to the pre-image and the corresponding point on the image have equal length.
